Rita Ora Juggles ‘Jingle Bell Rock’ and Stony Silence

RING MY BELL: Decked in a Santa-inspired marabou-trimmed rubber bra and matching skater skirt, Rita Ora hams up a version of “Jingle Bell Rock” for Love magazine’s annual Advent calendar — but quickly lets her true talent shine when things go wrong.

Ora, currently a judge on The X Factor, lip syncs and dances to the version from the 2004 film “Mean Girls” in a black and white video directed by Sam Faulkner, released on Saturday.

The video features Ora and a vintage boom box blasting out the song. When it breaks, she finishes it a cappella in her unmistakable raspy voice, dancing around in paisley appliqué stiletto sandals by Giuseppe Zanotti.

Love editor in chief Katie Grand said she’d always wanted to do a pastiche of “Jingle Bell Rock” and last year had asked Lindsay Lohan to do it, but no one could find a boom box that morning, so it never happened.

“This year, Rita agreed to take part in the calendar and she did the song in one take — she was really good,” said Grand.

After Ora finishes singing, she lifts up her skirt, flashes her underwear and tosses down her Santa hat. All in a day’s work.

Now in its fifth year, the humorous calendar features short videos starring the likes of Alessandra Ambrosio, Daisy Lowe, Gigi Hadid, Hailey Baldwin, Immy Waterhouse, Irina Shayk, Kris Jenner, Kendall Jenner, Miranda Kerr, Pamela Anderson and Poppy Delevingne.

According to Grand, the daily videos are less about Christmas — and more about the fertile imaginations of those involved. “Pam Anderson wanted to do a B-movie and wear a big, black beehive wig,” said Grand. “Kendall wearing a shark’s outfit was an obsession of mine.”

Unlike most Advent calendars, Love Video Advent 2015 lasts for all 31 days of December. “It’s not very religious in theme, so I thought it would be more appropriate to do the whole month rather than 24 days,” said Grand.
