The Ex Factor! Lovesick Prince Harry Launches All-Out Mission To Get Cressida Bonas Back—Find Out What He Did For Her On His Birthday

The Prince, fifth in line to throne, kicked off his 31st birthday in Sussex on Sept. 15 with some pals, but couldn't wait take flight to go meet ex-girlfriend Cressida Bonas, 26, later that evening in London. We don't know about you, but any man who hops a helicopter to go see a lady on his birthday, that's some royal love in the making (er, remaking?).

Now, there's a lot of whispering going back and forth in their camp about the pair trying to rekindle their two-year romance that ended last year in April—crushing recent reports that Harry has hooked back up with his high school sweetheart, Chelsy Davy. Hardly likely, since him and Cressida were spotted at the Cross Keys pub in Chelsea cozier than ever with many of their mutual friends, and Chelsy nowhere to be found.

"Their time apart really brought home to him how perfect she is for him," the source says. "It took him a while to understand it, but he knows now that Cressida is the only one for him," a source told Star.

Star readers know their split anchored on the reason that the aspiring actress felt stifled by the attention that came with dating the world's most eligible bachelor—even causing roadblocks in her career while dating him. But now, the 26-year-old actress just landed a big debut in a new show called Doctor Thorne, a new period drama from the creator of Downton Abbey, which says her acting reputation seems to be on track—so what's holding her back from Harry now? Not much from where we're standing!
