Last week the famous exes were caught together supposedly celebrating her birthday. Now US Weekly is reporting they may not have gotten over each other yet. Here's more:

Leonardo DiCaprio and Gisele Bündchen, who called it quits last November after an on-again, off-again five-year relationship, “started hooking up again about a month ago,” a Bündchen pal tells Us. Despite the fact that since December, DiCaprio, 31, has been dating model Bar Refaeli, 21, he and Bündchen, 26, “never really got over each other,” the source says.

Tongues started wagging that the exes had gotten back together when DiCaprio showed up at Bündchen’s 26th birthday party in L.A. last week, but the source tells us that’s not the case.

“They’re not talking about getting back together. They just care for each other.”

Still, Refaeli’s mom, Zipi, assures Us that nothing between her daughter and DiCaprio is awry. “Everything is very OK,” she tells Us. “They’re fine.”

We actually like Leo and Gisele together. Maybe they just needed a break. More sexy pictures of Gisele, Heidi and Alessandra backstage at a Victoria's Secret party so
