Joe Jonas, enjoying a romantic dinner with girlfriend Ashley Greene at Koi in L.A. The couple, who kissed and held hands from the minute they walked in, were in a “relaxed mood,” an onlooker says. The two ordered a round of drinks – sake for him, a pumpkin pie martini for her – with their dinner. What else was on the menu? Champagne – for fellow diners Lady Antebellum since Jonas, a big fan of the band, sent the group a bottle of Dom Pérignon.
