Ariel Winter is ringing in the holidays with a little Sexy Santa action!

The Modern Family star wore a super-short red velvet Santa coat, showing off some serious leg, as she posed solo and with boyfriend Levi Meaden in these Instagrams. Her beau, in a black suit, put his arm around his lady for the photo captioned, "My Christmas #mcm."

The 18-year-old first debuted her leggy look a week ago in the solo shot but the recent pic is further confirmation of her relationship with Levi, 29, an actor in the Netflix original series The Killing.

As usual, Ms. Winter was showing off her cleavage as well, despite have her breast size reduced from an F cup to a D cup last June. And she looks spectacular -- this is gonna be a happy Winter for Levi!
