Channing Tatum Jenna Dewan-Tatum welcomed their first child together in London on May 30, Us Weekly confirmed.

The child's gender is not yet known.

Tatum, 33, and Dewan-Tatum, 32, announced they were expecting their first child in December. The couple met on the set of Step Up in 2006, and got married in July 2009. The couple relocated to the United Kingdom for some time while Channing is filming Jupiter Ascending.

Production of Tatum's new film is set to move to Chicago in July and his wife will begin work on her fall Lifetime series, Witches of East End, in Vancouver around the same time.

"The baby will get top billing as far as priorities go," a source told the magazine. "Channing is going to be the most adorable hands-on daddy ever and do whatever is necessary to make sure Jenna can balance it all."

"Who knows what kind of parents we'll be?" Jenna told the May 2013 issue of Glamour. "We have two dogs, so we've had some practice! And as soon as this baby comes into the world, Channing and I will figure it out real fast."

She talked about balancing motherhood and her career by saying, "I have no idea what I'm up against. But I'm as mentally prepared as I can be."
