Posh and Becks are set to join in a $198,000 (£100,000) bash for J.Lo’s twins. Tom Cruise and Katie Holmes are hosting the party at their home. And the Hollywood Hills do is set to be a showbiz extravaganza. Tom and Katie have arranged a Welcome To The World theme for Jennifer Lopez and Marc Anthony’s newborn boy and girl.

As well as a pink and blue theme – including pink and blue cakes – they’ve invited showbiz pals like Victoria, 33, and David Beckham, 32, Eva Longoria, 32, and John Travolta, 54.

The mole added: “While David and Victoria can’t promise to be there because of David’s football commitments, they’ve offered to help any way they can. Katie has even organised for children’s entertainers to go along and is setting up a special Playstation games room for them.”

We reckon they’ll even have to set up a separate room to accommodate all the plush gifts Jennifer, 38, and Marc, 39, have received.

The mole added: “Jennifer and Marc have been bowled over with so many congratulations messages, cards, flowers, balloons, you name it.

“They have also been sent many gifts from family, friends and fans.”

Not to mention Tom­Kat’s perfect present… a giant fish tank.

We’re told: “Tom and Katie wanted to get them something different and special so they thought a giant fish tank would be great.” Considering recent reports that the babies’ nursery is ocean themed, we reckon it’ll definitely fit in.

Jen gave birth to the twins last week and was “thrilled” at becoming a mother for the first time. Husband Marc already has three children.
