Contrary to reports, Hudson told Elle she is not engaged to Rodriguez. But the actress has become a fixture at Yankees games, cheering the slugger all the way to the World Series. In August, she brought her mom, Goldie Hawn, and Hawn's longtime partner Kurt Russell, whom she calls "Pa," to see the Yankees play the Boston Red Sox.
Hawn was reportedly cool on the relationship when it started in May. A source told Britain's Daily Mail that Hawn wanted her daughter to settle down and leave the dating scene.
"Kate's had a string of boyfriends since her divorce from Chris Robinson and it's always the same pattern -- she falls hard and fast, then gets bored or has her heart broken," the source said. "Goldie hates the idea of seeing Kate getting hurt again."
Sansing believes if Hawn was initially cool, she has since come around. "Goldie is extremely supportive of her daughter," she said. "They are very similar people, with similar personalities, looks and careers. She could pull a Goldie and end up with A-Rod for 20-something years and never marry."
Like her mother, Hudson fell initially for a rocker. She was just 21 and a breakout star for her role in "Almost Famous," when she married Robinson, 13 years her senior.
"She married a guy that nobody thought she would marry," Sansing said. "He didn't look the part of the husband of a Hollywood star."
The pair met at a party in New York City in May 2000, and moved in together four days later. But the relationship was often rocky. "In the beginning we were so volatile," Hudson told People magazine in 2003. "We were so in love and passionate, and then we would just hate each other and throw stuff around, and then we would travel to Paris for a week."
After her breakup with Robinson, Hudson rebounded with her "Me, You and Dupree" co-star Owen Wilson.
"Owen was seemingly the perfect match," Sansing said. "They were both blond beauties, loved to be at the beach, free spirits. But what seemed to be perfect on the outside turned out not to be."
Hudson has reportedly dated other actors, including Dax Shepard and Matt LeBlanc and was even linked with her "How to Lose a Guy in Ten Days" co-star Matthew McConaughey.
But it was McConaughey's running buddy, cycling champ Lance Armstrong, that Hudson really clicked with.
"She and Armstrong also seemed unlikely," Sansing said. "He was totally outside of Hollywood. But they were both coming out of relationships (he with Sheryl Crow), they both have kids, they're both athletic. You saw them playing tennis together and getting their families together."
Sansing is not surprised to see Hudson linked with athletes, including NHL star Eric Lindros and golfer Adam Scott. "She's someone who likes the outdoors, she likes to do things," she said. "You always see her running, biking, skiing with her family every year. She's drawn to these athletes because it's part of what she loves."
While Hudson's love life has taken center stage, her career has seemed to suffer, with her most recent films, "Fools Gold," a reprise romantic comedy with McConaughey, and "Bride Wars," with Anne Hathaway, tanking at the box office.
"Everyone really wanted her to be the next America's sweetheart. We needed a new Julia Roberts and Meg Ryan," Sansing said. "'How to Lose a Guy' was a sleeper success. Then she had a bunch of movies that petered out."
"But Hollywood can be very forgiving," she added, "and she's one movie away from being a star again."
