Newlyweds Beyonce Knowles and Jay-Z's wedding celebrations won't be stopping anytime soon - if the couple's appearance in Hollywood on Wednesday is anything to go by.

The couple partied with 40 friends and family at a private dinner held at the Hollywood Roosevelt Hotel's Tropicana Bar after Jay-Z's sold-out show at the Hollywood Bowl.

Beyonce wed Jay-Z on 4 April, but have yet to confirm they are man and wife - even refusing to wear wedding rings when out in public.

Knowles turned up to Wednesday's private dinner with former Destiny's Child bandmate Michelle Williams, who was reportedly a bridesmaid at her New York wedding.

Other guests included Knowles' mother Tina, sister Solange, Jay-Z's touring partner Mary J. Blige and new mum Christina Aguilera.

A hotel source claims Jay-Z sat by Knowles' side all night and the couple looked "very happy," cuddling each other and openly showing their affection for each other.

Lindsay Lohan's DJ pal Samantha Ronson provided the music for the private party.
