Big Sean and his fiancee, Naya Rivera, are getting into the holiday spirit. The newly engaged couple unveiled the sexy Christmas card they'll be sending out to loved ones and friends.

As revealed on Just Jared, the Detroit rapper is dressed to the nines in a slick black tuxedo and matching shoes. His gorgeous wife-to-be is wearing a glittering red gown -- designed by Diane Von Furstenberg Julian -- that reveals her long, slender legs and thighs.

In a close-up photo she posted on her Instagram page (see above), Rivera also dons diamond-encrusted snowflake earrings and a matching necklace, plus she reveals some cleavage. Oh my!

It makes us wonder if the 'Glee' star was naughty or nice this year. Judging by Big Sean’s sly grin, we guess the former.

The hip-pop couple have only been engaged for a few months but they are already gathering ideas for their wedding.

In an interview with People, Rivera says that she and Sean are having fun with planning the nuptials.

"At the end of the day, he knows 'happy wife, happy life!'" she said. "So, he's kind of like, 'Whatever you want, babe!'"

"He's so involved," she added. "We definitely bounce things off of each other [and] we're always on the same page about everything, which is probably why we're getting married."

The 26-year-old actress still hasn’t found her dream wedding gown just yet, but she’s in no rush at this point.

"It's going really well," she says. "It’s fun. It's obviously something that I've never done before, but it's so fun. Whatever happens will happen. Right now we're just so in love and really looking forward to spending the rest of our lives together."

Merry Christmas, Big Sean and Naya Rivera!
