Katy Perry misses Rihanna's wild 23rd birthday celebrations
The S&M singer was famously absent from Katy's wedding to Russell Brand in October and Katy also found herself too busy to party with Ri-Ri.
'I missed ur WEDDING!! This is small stuff boo! #whenworkcalls.'
Rihanna's lavish bash was held at a private Beverly
Hills residence and featured two huge ice sculptures - a fish and the
letter R - with trays of velvet cupcakes and stashes of sweets.
The birthday girl wore a peach bodycon cut-out mini dress with purple
tassles and partied with Snoop Dogg, Zac Efron and Cee Lo Green.
'Go grawl, its ya birthday, ITS PARTY TIME! All my bestfriends are here!!!!' Rihanna wrote in a subtle dig at Katy.
'And my BRO!! Wish u cud see how SICK this sh*t is!!! #Staytuned.'
