Tom Cruise and Katie Holmes are set to host a $200,000 party to celebrate the birth of Jennifer Lopez's twins.

The 'Top Gun' star and the former 'Dawson's Creek' actress are good friends with J.Lo and her husband Marc Anthony and have arranged a 'Welcome to the World' bash for the couple's newborn boy and girl.

A source said: "Tom and Katie are thrilled for Jennifer and Marc and have offered to throw a party for the twins next month."

The party at Tom and Katie's Los Angeles home will have a pink and blue theme and guests expected to attend include John Travolta, Eva Longoria Parker and David and Victoria Beckham. The soccer ace and his Spice Girl wife have offered to help Tom and Katie with the baby bash.

Meanwhile, David and Victoria have been getting advice from Tom on adoption.

The couple - who already have three sons, Brooklyn, eight, Romeo, five, and three-year-old Cruz - are keen to have a daughter and are reportedly considering adoption. Tom has two adopted children, a daughter Isabella, 15, and 13-year-old son Connor, with ex-wife Nicole Kidman.

A source said: "Victoria definitely wants a girl but she's not sure she wants to go through a fourth pregnancy."
