Meanwhile rumors were swirling that Cox has been having a more-than-professional relationship with Brian Van Holt, 40, her co-star on her ABC comedy "Cougar Town." RadarOnline.com quoted an unnamed source saying that Holt and Cox often spend time together off-set.
Halle Berry and Gabriel Aubry
Actress Halle Berry, 43, and model Gabriel Aubry, 34, tried to keep their May breakup amicable, but the Internet was still abuzz.
Aubry told "Access Hollywood" through a release from Wilhelmina Models that he has "only love and respect" for his ex, with whom he has 2-year-old daughter, Nahla.
"She is, and will forever be, one of the most special and beautiful people that I have ever known," Aubry said. "While I will not comment on all of the wild inaccuracies being speculated about in the media, I am sad to say that Halle and I have decided together to separate at this time."
People magazine reported a slightly different, and messier, breakup story, using information it acquired from an unnamed source close to Berry.
"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."
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 Carrey.
"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.
But the toll of McCarthy dealing with her son Evan's autism and Carrey's long battle with depression may have finally cost the couple their relationship.
Sandra Bullock and Jesse James
Less than two weeks after Sandra Bullock received her best actress Oscar, a bombshell, in the form of tattoo Michelle "Bombshell" McGee hit her marriage. Bullock was assailed by a flood of reports that her husband Jesse James, had multiple affairs.
It spelled the quick demise of their marriage. Beginning in March, Bullock moved out of their Los Angeles home, filed for divorce and began proceedings to adopt as a single mom a baby boy named Louis.
By August, both appeared to have moved on. James was linked to celebrity tattoo artist Kat Von D., while, for single mom Bullock, there was only one man in her life -- son Louis.
"We have both moved on with our lives and only want the best for each other," she told People magazine. "Anything else that is said on my behalf is inaccurate."
