Adorable over omelets!

Blake Lively and her older sister Robin had a double date with their respective beaus on Saturday in NYC, a source tells Us Weekly. Blake, 24, and Ryan Reynolds were "very cuddly" at the Stanton Social and shared a booth with the Gossip Girl star's big sis and her hubby.

A source adds that Blake "hit her head on a lamp as [she sat down in the booth] and put a napkin jokingly on her head."

The foursome shared a breakfast of donuts, huevos taco, bacon, egg and cheese biscuits and muffins. According to the source, they were "poking each other, giggling, and even seen leaning on each other in the booth."

The Lively sisters and their guys were "very sweet, polite and gave a generous tip."

Later on Saturday, the couple was spotted shopping for jeans at John Varvatos. According to blogger Just Jared, they were "hand in hand" and shared a kiss outside the dressing room.

That night, Blake and Reynolds, 35, grabbed dinner and dessert at Serendipity. According to a source, duo were joined by two friends around midnight and both had peanut butter frozen hot chocolates.

"Blake sat very close to Ryan and had her head on his shoulder the entire time," adds the source. "Blake has been a regular at Serendipity for years."
