Megan Fox films cameo for husband's show

New mum Megan Fox has returned to her TV roots to give her husband Brian Austin Green's new US show a big boost - by filming a guest appearance for the comedy.

The Transformers star has shot a cameo for The Wedding Band, about four friends who spend their spare time performing at cheesy parties.

In an upcoming episode, which will air in the US on Saturday, Fox will play a guest at a Comic Con-themed wedding ceremony, who flirts with Green during the reception.

The real-life husband and wife will have no problem conveying their chemistry onscreen - they previously worked together on US sitcom Hope & Faith in 2004, when the couple first met.
