Rod Stewart's pregnant fiancee Penny Lancaster almost missed a glitzy Hollywood party on Thursday night (06OCT05) when her mini-dress split.

The rocker's pregnant blonde love was getting ready at home before the Spago party, held to celebrate the 20th anniversary of CNN newsman Larry King's daily show, when the wardrobe malfunction took place.

Speaking at the party, Stewart revealed, "She had a little short number on and she bent down to do her shoes up it just split down the front."

Fortunately, Lancaster was able to find a more fitting outfit for the party.
