Ashley Greene and Joe Jonas Get All Lovey-Dovey on Date

Couple steps out for sushi and can't hide their affection during dinner

Can you feel the love between Ashley Greene and Joe Jonas?

Fellow diners at Katsuya in Los Angeles certainly could when the two stepped out for a sushi date this week.

Although the two requested to be seated at a private table, people couldn't help noticing their PDA:

"If Ashley sat any closer to Joe, she would have been in his lap!" one onlooker commented.

The tight twosome ordered yellowtail with jalapeno and drank Kikusui sake, since Joe's now 21 and legal.

And instead of ordering dessert after their cozy meal, they just had each other.

"They stayed behind after their dinner for some cocktails and kisses before sneaking out the side door," a source says.

Wonder if we'll see Joe visiting Ashley on set in New Orleans when she gets back to work on Twilight? Fingers crossed!
