Kate Hudson and Nick Jonas: Together Again!

Kate Hudson and Nick Jonas were busted by The National ENQUIRER last night trying to make a quiet exit from Pace Restaurant, a cozy Italian place in L.A.’s Laurel Canyon. The on-again/off-again pair shared a romantic four-hour dinner that onlookers described as filled with PDA. Are the (rumored) lovebirds cooing together again?

Nick, 23, and Kate, 36, were both at DirecTV’s Super Bowl party last Saturday — where they reportedly shared a passionate kiss and set tongues wagging that they were once again an item. The sexy duo were first seen together back in September. They refused to confirm any relationship (other than being friends) and appeared to cool things off last month.

Both parties have been adamant in recent interviews that they are single — but then came last weekend’s lip-lock at the Super Bowl party at Pier 70 in San Francisco. Eyewitnesses reported that Nick approached Kate, and they talked for about 45 minutes. In a potential disaster scenario, one of Kate’s other exes — “Dancing With the Stars” hoofer Derek Hough — also made the scene! But onlookers said Kate handled it with grace, — at one point talking to both handsome guys at the same time! But she eventually left with Nick!

The star of “Almost Famous” and the “Jealous” crooner attempted to sneak out the back door of the eatery without being seen — but our cameras are everywhere! The A-listers tried to hide their faces as they dove into a waiting SUV, but we did manage to get some clear shots of their very pretty mugs!

The undercover couple — who were introduced by Kate’s older brother Oliver Hudson, despite her being 13 years older — were last snapped together in public at California's Mammoth ski resort in January, and put their relationship on ice shortly after.

The “fool’s Gold” star, who is set to release her first book, “Pretty Happy: Healthy Ways To Love Your Body,” has son Ryder, 12, with ex-husband Chris Robinson and 4-year-old Bingham with ex-partner Matt Bellamy. Nick was linked to an old friend, actress Lily Collins, as recently as Jan. 30, but her very famous father, drummer Phil Collins, insisted the pair are just friends.
