Ryan Seacrest was in full holiday-gifting spirit Monday night. While dining at Abe & Arthur’s with Rob Thomas, Seacrest sent over a $1,000 bottle of Dom Perignon to John Legend‘s table with a candle wishing him a happy birthday. Legend then invited him to join his celebra tion downstairs at club SL, where the “American Idol” host’s generosity continued — he sent over another bottle of Dom Perignon to Ludacris‘ table. And at the end of the night, Seacrest left a $5,000 tip. Others at Legend’s birthday bash included Zach Braff, Lindsay Lohan, Kid Cudi, Estelle and Ryan Leslie.
