Celebs And Their Kids Step Out For Ben 10 Launch

On Saturday, ParentDish was invited to Leicester Square in London, where the whole place had gone green to launch the new TV series of Ben 10: Ultimate Alien, and the DVD of Ben 10: Alien Swarm. Many celebrities and their families came along too to watch their favourite cartoon, walk the green carpet and get stuck into the green candy floss.

So who was there?

If you were watching The X Factor on Saturday, you might have seen Sinitta helping Simon Cowell choose his finalists. But that was clearly filmed some time ago, because as you can see Sinitta was in London on Saturday. She came along to the event with her two children, Zac and Magdalena.

Sinitta's already told us how much she loves being a mum, and who can blame her with this cute pair. Making up the family portrait here is Sinitta's boyfriend, Angel Champagne millionaire Stefano Zagni.

Another X Factor star to put in an appearance was Stacey Solomon, seen here with her son Zachary. Stacey's signature blonde hair has now gone, and she's morphed into a more sophisticated new brunette look. Suits her, don't you think?

But they weren't the only stars and their mini-mes on show...

Spaced and Doctor Who star Jessica Hynes was there with her three children.

Nell McAndrew's little boy Devon had a whale of a time and loved the Ben 10 mask from his goody bag. Or is his mum protecting his privacy?

Will Mellor attended with wife Michelle and their two children Jayden and Renee.

Star of This is Englad 86 Stephen Graham brought the whole family along

Radio 1's Sara Cox was there, looking fab less than six months after the birth of baby Renee. She and eldest daughter Lola enjoyed the green popcorn.

And if you're wondering when the new Ben 10 series is starting - it's 10am on 10/10/10 (of course!), on Cartoon Network
