Beverly Hills Reese Witherspoon Deacon Phillippe flag football

Touchdown!

Pregnant Reese Witherspoon showed off her growing baby bump in a pretty blue dress as she watched son Deacon play a game of flag football in Brentwood, on Saturday afternoon.

The Oscar winner was accompanied by hubby Jim Toth, and the pair cheered enthusiastically as her eight-year-old played the game, while Reese held an energy drink for her little guy.

Despite the fact that the couple hasn't officially announced that the This Means War star is pregnant, there's no denying that growing bump!
