If YOU were rich...who would perform at your wedding?? Wow...so cool! Two Russian-Armenian scions were married in a lavish Hollywood-themed ceremony... and guess who they got to perform? LADY GAGA!
The $10 million wedding was held in L.A.'s famous Dolby Theatre, where Gaga was a surprise guest.
Check out these photos of the dress, cake and even a video of Gaga's performance where she sang "Poker Face" and "Bad Romance." #jealous ha
