George Clooney is allegedly headed for divorce from his wife Amal Alamuddin over his close relationship with his "Gravity" co-star, Sandra Bullock.

A source from Naughty Gossip claims Bullock is allegedly head over heels in love with Clooney and acknowledges him as "the one that got away."

Bullock allegedly feels she missed out on her chance to spark a romance with Clooney while the two were filming "Gravity."

"Sandy really likes George. All her friends know that he was the one, but for some reason it never happened," says the Naughty Gossip source. "After a few drinks all she does is talk about him, but now he is married she has far too much respect to mess with that."

Though Clooney has not publicly expressed any romantic feelings for Bullock, he did describe the Academy Award winner as "incredibly charming" and suggested Bullock is someone he has grown to care for given their 20 years of knowing each other, as they both later garnered their celebrity status.

"Every time we're together it's funny. She's somebody I adore, really, she's just fun to be in a room with. I'm sure people will assume people aren't quite who they appear to be on screen--they're shorter or taller or meaner or dumber--but Sandy is exactly what she appears onscreen, an incredibly charming woman who's really just fun to hang out with," Clooney said in a Reddit AMA in 2014. 

Meanwhile, a new report from the National Enquirer is refuting claims of tension between Aladmuddin and Bullock, insisting the two are actually friends, and Alamuddin has allegedly "made it her mission" to find Bullock a man of her own.

"Lawyer Amal, 36, and Oscar-winner Sandy, 50, have been in constant contact since then, connecting over everything from clothes to kids," said the National Enquirer. "Amal's been giving the actress fashion advice and even offered to babysit her five-year-old son, Louis."

Alamuddin and Clooney have yet to publicly respond to the divorce rumors. Bullock has also not responded to the romance rumors between her and Clooney.
