Katy Perry and her fiancé Russell Brand marked their engagement by throwing a huge do.
The couple were joined by some 50 friends and family at Il Cielo in Beverly Hills.
'They had a lovely soiree,' a source tells People.
Katy, 25, and Russell, 34, had the venue decorated with candles and red roses.
And guests were treated to a personalised white chocolate cake for dessert.
The comedian proposed in India on New Year's Eve.
The Cartier ring features a two-carat rock embedded on a thick gold band.
