Channing Tatum and wife Jenna Dewan-Tatum have welcomed their first child, reports US Weekly. No word on the name or gender of the baby, which was born Thursday in London. "We're going to actually have the baby in London while I'm shooting, and then there will be no downtime whatsoever after that," Tatum said in an earlier interview; last year's Sexiest Man Alive is currently shooting Jupiter Ascending. The couple, who met on the set of 2006's Step Up, have been married since 2009. Click for more celeb babies of 2013.
