CHANNING TATUM's pregnant wife Jenna celebrated the impending arrival of their first child at a special baby shower with her actress friends and fellow moms-to-be, JAMIE-LYNN SIGLER and JOANNA GARCIA SWISHER.

The expectant mothers, including 7th Heaven star Beverley Mitchell, gathered at Soho House in West Hollywood on 3 March (13) to toast Jenna Dewan-Tatum's bulging belly and guests were treated to vanilla cupcakes as they played trivia games all about the Step Up beauty.

Gushing about the party, Mitchell says, "Everytime we see each other, we get a little bigger. We're all so close, it's fun being pregnant together."

And Dewan-Tatum, who has decided not to find out the sex of her unborn child ahead of his or her birth, will be well-prepared for the baby's arrival, thanks to the pile of gifts she received at the shower.

A source tells Us Weekly, "Jenna got everything from a swanky stroller to cute little socks."

The get-together was planned months ahead of the tot's summer (13) due date as the couple is preparing to jet off to London, where the baby is expected to be born as the Magic Mike hunk shoots his new movie, Jupiter Ascending, in the city.

The insider adds, "Jenna wanted to have the shower with her friends while she still could."
