It's Katy Perry, with grandma Ann and hubby Russell Brand.
The group had quite a busy schedule yesterday. First, they saw Cirque do Soleil's Viva Elvis with 15 friends and family members.
"They drank white and red wine and were on their feet dancing," a source says.
After the show, it was off to dinner at Strip House in Planet Hollywood, followed by trying their luck at the blackjack table inside the casino.
"Happy 90th birthday grandma HUDSON! You're the reason why!" Katy tweeted yesterday.
Sounds like a happy b-day, indeed.
