The Material Girl traded up her unitards for a bit of camo and a paintball gun over the weekend.

To celebrate her son's 14th birthday, Madonna took Rocco and a crew of his friends to paintball in the Cote d'Azur on Sunday -- and it looks like the group had a blast!

Along with the celebratory snap in which Madonna is holding a paintball gun and punching the air, the 55-year-old wrote, "Birthday Shoot out!!!!! No one cheated!"

We're glad none of the boys cheated -- because we think they'd be no match for the likes of Madge!

The fam must love paint balling together -- for Rocco's 13th birthday last year, they all went paint balling in a forest outside of Cannes.

We still can't believe Rocco's 14 years old already!
