Lachey performs at actors' wedding

Nick Lachey is rumoured to have sung at the wedding of actors Will Yun Lee and Jennifer Birmingham.

The event was reportedly attended by a number of other celebrities, with Birmingham's bridesmaids claimed to have been Vanessa Minnillo, Kate Beckinsale and Rachel Reynolds.

Following the marital ceremony, it is believed that Lachey then serenaded the newlyweds.

"Nick sang one of our all-time favourite songs, 'Wonderful Tonight'," Lee told People after the event. "But he changed up some of the lyrics to make it really personal, it was amazing."

Earlier this year, it was announced that Lachey had parted company with his record label Jive.
