John Travolta and his wife Kelly are thrilled to be expecting another baby.

The Hollywood superstar and his actress wife announced the jovial news on Travolta's official website last night. The mum-to-be, a well-rounded 47, is reportedly three months pregnant. What are the bets it'll be twins...

It will be the third child for the couple, whose teenage son Jett died in early 2009 after a massive seizure at the family's Bahamas holiday home. They also have a daughter Ella Bleu, 10.

Confirming the news, Travolta told fans on his website: "It's impossible to keep a secret... especially one as wonderful as this. We want to be the first to share this great news with everyone that we are expecting a new addition to our family. Love, John, Kelly and Ella."

That might make up for the fact that their two beloved pet dogs were accidentally killed in a freak airport accident in Maine last week.
