Angelina Jolie apparently let her 10-year-old son Pax buy a "swearing finger" toy in Las Vegas.

According to Us magazine, the 38-year-old mum-of-six took five of her six children for Cinemacon in the Sin City where they visited Bonanza Gifts.

The store's manager Angie Hurt said that the kids were having a good time filling up their baskets with toys, when Pax bought a phonic operated Swearing Finger that flips off and swears a lot.

Although Jolie raised her brows at the toy, she didn't object, Hurt added.
