Lindsay Ellingson, Chrissy Teigen, Snooki and Other Celebs Ring in the New Year

As Ryan Seacrest tweeted, it’s “always great spending new year's with friends.” Of course, the friends he partied with on New Year’s Eve were “@Pitbull, @JustinBieber, @SantanaCarlos.”

Demi Lovato looked more like Jessie J as she tried on a sleek bob wig before hosting MTV’s NYE. “Hey guys... Like my new look? :P” she tweeted—well do you?

One would imagine that if anyone were to go hard on New Year’s Eve, it would be party girl Snooki. She surprised her Twitter followers with this pic of her low-key (and lovey-dovey) night. “This is how I spent nye. Sick, in pajamas, loving the guy that means the world to me,” tweeted Snooki.

Hilary Duff shared this photo of herself getting festive with Santas’s littlest helper. “Happy holidays from the three of us!! @HaylieK what would I do without you and your artistic ways!” tweeted the mom-to-be.

“Barcelona, you've won me over. I'm in love. #sadtoleavebutmustgoonward,” tweeted world traveler Dianna Agron.

Rihanna spent the holidays at home in Barbados, catching up with family like her cute old grandma who it looks like she took shopping. “#GmaDolly #BadBitchStatus,” tweeted the We Found Love singer.

Heidi Klum shared pics of her white Christmas on the slopes with husband Seal.

“Happy New Year!! I wish everyone a safe, happy, fun, successful and peaceful 2012! Xoxo,” tweeted model Lindsay Ellingson.

Model Jacquelyn Jablonski’s family fed her addiction for the holidays. “Guess my family found out about my coffee obsession?” she tweeted, displaying her caffeinated gifts.

Chrissy Teigen felt sorry for herself on New Year’s Eve: “Happy new year from me, alone in the dressing room, drinking away 2011,” tweeted the swimsuit model.
