Celebrating his 28th birthday in West Hollywood, Adam Lambert was spotted at the Grammy Style Studio Day 3 on Friday (January 29).

Dressed casually in jeans and a t-shirt, the “American Idol” star looked to be having a great time at the party ahead of this Sunday’s Grammy awards.

Much later in the evening, Mr Lambert took to his Twitter page to bid his fans goodnight, tweeting, “Going to bed! doing a crazy shoot for PAPER MAG @ 8am lol. I should keep on my hair&make and arrive already beat.”

Meanwhile, during Sunday night’s Grammy awards show, Adam will be working the red carpet as a fashion correspondent for E! - dishing his thoughts on celebrity style.
