"She kicked him out months ago because he wasn't able to pull his weight in the relationship, and she wanted to move on," the source told People.
According to Us magazine, Berry focused on Aubry's career disappointments, such as his failed New York City Cuban restaurant, which closed after two years.
"Halle called him a loser," a source told Us. "She'd rub it in his face that she's an Oscar-winning actress, and he's just a model. He couldn't take it anymore."
Over the weekend, Berry seemed to be enjoying herself while in Manhattan, despite the breakup. According to Us Weekly, the actress took in the Broadway show "Fences," starring fellow Oscar-winner Denzel Washington. On Saturday, she was the co-host, along with Jessica Biel and Jessica Alba, for the 13th annual Entertainment Industry Foundation's Revlon Walk/Run for Women with breast cancer.
The couple was not married but had been together for five years after first meeting on a Versace photo shoot. As recently as 2009, Aubry was quoted in In Touch magazine as saying he would like Nahla to have a sibling.
Perry said that the split may have had to do with the couple's 2-year-old Nahla, and the stress a child puts on a relationship.
"Having a baby can really change a relationship," Perry said. "It can put a lot of pressure on a couple and maybe that pressure was too much for them. Also, she could have just got tired of him; she has already been seen with two other guys this week."
Sandra Bullock and Jesse James
It appears the women who'd reputedly had affairs with James had the need for some emotional spring cleaning, given the flood of infidelity claims that started in March.
Last month, Bullock did her own spring cleaning by telling People magazine that not only had she filed for divorce in Texas, she had adopted a 3½-year-old baby boy, whom she named Louis Balbo Bullock.
Bullock told the magazine that the adoption began four years ago, and that the baby was brought home in January. The couple decided to keep the adoption quiet until after the Oscars. Once the scandal broke, James allowed Bullock to move forward with the adoption as a single mother.
Unlike a lot of the other couples who have split, Perry said that this was not really a case of spring itch.
"Jesse may have had a desire to be in a monogamous relationship, but he obviously didn't have a desire to maintain that monogamy," Perry said. "Sandra recognizes the need for a clean break, and she has not bad-mouthed him at all. She has just been very decisive and is moving on with her life."
Jim Carrey and Jenny McCarthy
Carrey and McCarthy announced the amicable end of their five-year relationship on Twitter.
In a statement to People magazine in April, McCarthy said that she was grateful for the years she'd spent with Jim.
"I will continue to be in his daughter's life and will always keep Jim as a leading man in my heart," McCarthy said.
Carrey tweeted a similar sentiment: "I'm grateful for the many blessings we've shared and I wish her the very best! S'Okay!"
The breakup came as a bit of a shock, considering that the couple was all smiles as recently as February when the pair hosted an event to support McCarthy's autism foundation, Generation Rescue.
"Jenny is the first person I have been with where I don't have a giant question mark over my head," Carrey told People on the red carpet of the event.
Now it seems at least one of them had a question mark.
