A year after captivating the world with the wedding of a century, Prince William and Catherine, the Duke and Duchess of Cambridge, seem to be stronger than ever.
The first year of marriage was an eventful one for the royal couple. They moved into Kensington Palace, got a dog named Lupo, spent six weeks apart while William flew a helicopter in the Royal Air Force and Kate made her first public speech.
Meanwhile, the world has been watching. Interest in the dazzling duo has remained strong with fashionistas, royal watchers and romantics dissecting their every move.
Experts weighed in on five signs the royal couple are still royal lovebirds.
|They break the rules with body language|
"They seem to have a glow about them when they're together," Judy Kuriansky, a psychologist at Columbia University better known from her radio show as Dr. Judy, told ABCNews.com. "They seem to be in tune. They're breaking rules together. That's almost a sign of bonding between them."
Whether they're at a charity event, public appearance, polo match or movie premiere, the Duke and Duchess have been known to sneak whispers and touches that defy royal protocol.
"Because we have very little report of what they say, it's mostly the body language," British relationship psychologist Susan Quilliam told ABCNews.com. "When they are together, they constantly sort of check in with each other and look at each other—the contact, smiles, little touches."
Quilliam said that some couples are so overly "lovey-dovey" that it can be a sign of the couple overcompensating for a problem in the relationship, but she does not see this with the prince and his wife. She said their affection seems to be genuine.
"It's not overboard," Quilliam said. "It's not a show and it's not borne out of insecurity."
|She gets along with the in-laws|
While Prince William was serving his six months of duty as a helicopter pilot for the Royal Air Force, Kate could often be seen at events with members of the royal family. Kate is often credited with reviving positive public opinion of the royal family.
"They must think she's a gift sent from heaven. She's bringing people back to the royal family, recovering the royal family's credibility," Quilliam said. "Kate and William are the royal family's salvation in many ways, and they love her."
Kate is often seen spending time with Queen Elizabeth and Prince Charles' wife, Camilla Parker Bowles, with whom she appears to have a close relationship. Kate is often sporting a bracelet that was a gift from Bowles.
"The Queen seems to adore her," Kuriansky said. "The Queen also adored Diana in the beginning. There's that pressure. You're always on eggshells."
Quilliam is confident that Kate knows what she's doing and is authentic in her motivations.
"She's a very socially competent young lady. She knew what she was getting herself into," she said. "She's clearly very much in love with him. She's not a gold digger. It's a real relationship that just happens to be developing in the context of the royal family."
|They're defying pressure to have a baby|
The first question on so many minds when it comes to Prince William and Kate is, When will they have a baby? The pressure is enormous for them to produce a royal heir.
"There's pressure on her to have a child. It's a miracle they've made it through a year because there was so much pressure on them," Kuriansky said.
Every time the couple makes an appearance where children are present, headlines abound about how comfortable they looked and any exchanged looks are scrutinized. When Kate drinks water instead of wine at an event, rumors swirl.
But Quilliam doesn't think they will cave to the pressure and will do things in their own time.
"I'm pretty sure they're not going to rush into that. They're sensible," she said. "They know that they need to take a couple of years. The arrival of the first baby is the first thing that tilts the balance in the marriage."
William was born about 11 months after his parents were married.
"Diana had no time to adapt to being married," Quilliam said. "They're giving themselves time to adapt before having children."
Though the couple is coy on their plans for a baby, they got a black cocker spaniel puppy named Lupo. The dog's name is derived from the Latin word for "wolf." The royals said they got the pup to keep Kate company while William was away, but experts say the dog could also be practice for having a baby.
"Number one, the dog is companionship for her. Number two, it's giving both of them a responsibility," Quilliam said. "It could well be a practice run."
|They coordinate their outfits|
The Duke and Duchess have been known to step out in coordinating outfits. Whether they're wearing matching purple cable-knit sweaters for a walk in the park or cowboy hats and button-downs for a visit to Canada, they are always complementary.
"The thing I always remember is when they came out of Westminster Abbey last year and there was an exchange between them, which gave me great hope from the get-go," Quilliam recalled. "She said to him, 'Are you happy?' And he said, 'Yes, you're my wife.'"
"They are interested in each other's happiness and they're happy to be married. It means something to them. It's not just a formality," she said. "They may hit bumps down the line, but I'm very hopeful."
The couple met at St. Andrews University, where they both studied, in September 2001.
It's believed the couple's fairytale began March 27, 2002, when Kate was selected to model a now infamous see-through dress in a student fashion show, which many say caught William's attention right away.
From then on, the duo was seen together often and they are believed to have begun dating in 2003 or 2004. They formally split in April 2007, but were back together by June of that year. They were engaged in November 2010 and married April 29, 2011.
|They thrive separately and together|
Many wondered what would happen when the Duke and Duchess were separated for six weeks this year, including their first Valentine's Day as a married couple, while he was performing his military service. But they've proved any naysayers wrong by demonstrating they thrive both together and separately.
"He's working and she's doing her work for the royal family," Quilliam said. "They have projects. They're not only preparing him to be king and looking towards starting a family."
Kate has impressed royal watchers by taking very naturally to her role as Duchess, getting comfortable with solo public appearances, delivering her first public address while William was away and selecting the charities she will support.
"She's growing into the role. She's not resisting or finding it too stressful," Quilliam said. "She's still feeling very motivated and feels that this is worth it because of the marriage."
Quilliam said the couple are taking their time and working at their marriage, which William's parents did not get to do. "Charles went back to being heir of the throne and Diana was thrust into it immediately," Quilliam said. "[William and Kate] are thinking, 'Let us solidify our relationship and then we'll be ready to take on a full royal role."
