Becca's already revealed she's currently engaged to one of this season's contestants ... but it's unknown which one. That's where these photos come in ...
Becca can clearly be seen kissing a man in a suit at the Shangri-La's Resort in the Maldives -- possibly her new fiance -- while filming at the location on May 10. We're told there was a big cheer, hugging and group photos taken after what appeared to be a proposal.
Our sources also say the crew held a party for the couple the next day at the resort.
