Kristin Cavallari has jumped from one hunk to another, as she's soothing the wounds from her breakup with fiancée Jay Cutler in a steamy new fling with her Dancing with the Stars partner, Mark Ballas, according to the new issue of Star magazine.
Things between Cavallari and Ballas have gotten really romantic since they began practicing for the show’s 13th season late last month, as one witness says the twosome "were all over each other” taking in dinner at West Hollywood's Marix Tex Mex Café last week.
“She was sitting on his lap while he was nuzzling her neck," the witness told Star. "They were having dinner with Derek Hough but didn’t pay him any attention. They were consumed with each other. You can tell she is really into him.
"Kristin was having a great time! They definitely look like more than friends!”
Less than a week earlier, a source told the magazine that the sexy dance duo "were definitely very comfortable together and extremely flirty" while celebrating The Abbey founder's David Cooley's Birthday in West Hollywood.
“By the end of the night they were being cuddly together in a dark booth," the source said. "They didn't leave each other’s side all night and were constantly holding hands and touching.”
Earlier this year, Ballas was been romantically linked to American Idol beauty Pia Toscano.
A source told Star Kristin was devastated by her July breakup with the Chicago Bears quarterback, "but she’s not the type of person to sit around and feel sorry for herself.
"She dusted herself off and went after the first hot guy who crossed her path -- that guy was Mark!”
We’ll see more of the new duo when Dancing with the Stars begins on ABC Monday, September 19.
