Here's what we know. Gigi Hadid and Cody Simpson have split up. The model then spent the weekend hiking in L.A. with Taylor Swift. On Wednesday, she was spied having lunch at Cheebo in West Hollywood with none other than Joe Jonas, sending tongues wagging that she may be rebounding with the singer. Here's what we don't know: Was her lunch date a date, or just lunch? How long has she been hanging out with Jonas? And, most importantly, does gal pal Swift know that Hadid's making moves with her O.G. bad boyfriend/songwriting muse? Let's not forget that Jonas was the first to activate Swift's scorned-woman schtick (see "Forever & Always"), way back when John Mayer and Harry Styles were all but a twinkle in Tay's eye. Hadid and Swift are tight, and the pop star is making her own sweet, sweet love with new boyfriend Calvin Harris. She probably doesn't care at all whether the 20-year-old beauty wants to date Jonas or not. Still, it certainly makes you wonder what they talked about on that hike. (Just Jared)
