You'll never guess who's come down with a case of love fever! That would be The Bachelorette's Ali Fedotowsky and her ex-fiance, Roberto Martinez, who reportedly flirted up a storm during Ashley Hebert and JP Rosenbaum's wedding on December 1 in Pasadena, California.

Roberto and Ali parted ways about a year ago, but it looks like they're still lucky in love. “Ali and Roberto hooked up after the rehearsal dinner,” a source tells Life & Style. “They have been talking recently and have been very amicable. They were very flirtatious with each other all night!”

Roberto and Ali spent the night at the same hotel, and were joined at the hip for most of Ashley and JP's reception. “They spent much of the wedding night by each other’s side,” the source reveals. “And a lot of guests noticed how flirty they were with each other."

So is a reunion in the works? "Roberto and Ali are still communicating,” the source says. “I wouldn’t be surprised if they got back together in the near future.”

Color us excited, Bachelor Nation! Do you think Roberto and Ali should give their relationship another shot?
