Jennifer Lopez and Casper Smart are getting a taste of Sin—Sin City that is.

The couple was out in Las Vegas last night where they did little to play down their sizzling romance...

Just one day after J.Lo and Smart were spotted shopping around Calabasas, Calif., the lovebirds had dinner at pan-Asian eatery Social House inside Vegas' CityCenter, where they were joined by the singer's American Idol pals Steven Tyler, Randy Jackson and Ryan Seacrest. The A.I. crew was in town taping an episode of the reality competition show earlier in the day.

The gang arrived at the restaurant around 8 p.m. and dined on pizza, Kobe hanger steak and yellowtail along with a round of Caymus cabernet wine.

According to a source, Lopez and her dancer beau were cuddled up next to each other and even exchanged a few small kisses while enjoying the hour-and-a-half dinner. At the end of the meal, Smart surprised Lopez by ordering her Social House's dark chocolate lava cake for dessert.

The "On the Floor" singer wasn't able to finish the sweet treat, but luckily the rest of the table pitched in to sample the delicious dessert.

"Thank you @socialhouselv for dinner," Smart tweeted. "Always delicious and a pleasure!!"

Lopez and Smart aren't the only boldfaced names who have been spotted out and about. Read on for more celeb sightings...
