Ashlee and Jessica Simpson got an early start on Christmas this year. On Friday, the sisters celebrated Ashlee's 30th birthday amid a Winter wonderland in LA. The party was complete with faux snow, Christmas lights, and even a blow-up snowman, all of which Ashlee's husband, Evan Ross, showed off on Instagram. "Last night made it @ashleesimpsonofficial favorite holiday Christmas in California," Evan captioned a snap with his wife and pals. "It was a snowy one. Happy birthday baby." Meanwhile, Jessica got in on the holiday spirit with an elaborate mask surrounding her eyes, which "took about 3 washes" to remove, she joked in her Instagram post.

Throwing memorable bashes is nothing new for the family. In late August, Ashlee and Evan tied the knot in a bohemian-themed wedding at the home of his mom, Diana Ross. The celebration came nearly two months after Jessica's lavish nuptials with Eric Johnson. Keep reading to see the crew's new snaps!

Jessica said it "took about 3 washes to get this fantastic mask off."

Evan shared this throwback picture with a sweet message for Ashlee. "I love you I love you. It's been such an amazing year. Happy birthday 2 my beautiful wife," he wrote.

Jessica posted this throwback picture to honor Ashlee on her special day, writing, "Happy Birthday Ashlee! There is no one I believe in more than you. Thank you for inspiring me everyday. I love you!!! #dirty30."
