Newlywed actor Kevin Zegers has been forced to postpone his honeymoon until after he completes promotional work for his new Mortal Instruments movie.

The Gossip Girl star wed his longtime girlfriend Jamie Feld in New Jersey on 3 August (13), but the happy couple will have to wait until the end of the month before they can jet off to the Turks and Caicos Islands for their first vacation as husband and wife.

Zegers will be busy promoting his new movie The Mortal Instruments: City of Bones around the world, but he will treat his new bride to a relaxing break before he starts shooting the second installment in the fantasy franchise.

He tells People.com, "We're actually doing the European (press) tour and then we go to Mexico City. Then my wife and I are going to go on our honeymoon before we start shooting the second movie."

Zegers' co-stars in the film, Lily Collins and Jamie Campbell Bower, were guests at the wedding, but the couple is rumoured to have split just days afterwards.
