Ariel Winter, 21, turns heads in low-cut white dress at Spotify party in LA

She's said she's ready for more grown up roles now that sitcom Modern Family is coming to an end.

And on Thursday night, Ariel Winter, 21, put on quite a show in a very low-cut dress at a party hosted by Spotify in LA.

The raven-haired actress fairly busted out of the petticoat-style number that hugged her curves.

Ariel sported hot pink polish on her finger and toe nails and stepped out in silver sandal heels. She carried a white purse decorated with ostrich feathers and accessorized with long diamond earrings. She completed her look with dramatic eye makeup and ruby red lip color.
