I think we can now assume that the reported Saturday party, was indeed on Sunday as there were many celebrities spotted at Via Veneto restaurant on last night to attended Victoria's 34th birthday party, hosted by David.
Kate Beckinsale and husband Len Wiseman
Sean "Diddy" Combs and Kim Porter
Sir Elton John and David Furnish
Usher and Tameka Foster
Gwen Stefani and Gavin Rossdale
Will and Jada Pinkett Smith
and of course Tom Cruise and Katie Holmes.
UPDATE: Heidi Klum was also there.
I guess this will put those rumours of a rift to bed.
There are a few surprise guests in there for me like Usher and Gwen Stefani.
Check out this video of them the guests here.
