Christina Aguilera & BF On Horse-Drawn Sleigh

Christina Aguilera celebrated her 30th birthday with her love Matthew Rutler in high, yuletide style on Saturday Dec. 18.

Sipping wine and wearing mouse-ear style earmuffs, Aguilera cuddled with Rutler in a white horse-drawn carriage; the duo stayed at Hotel le Lana, a luxury ski resort in Courchevel, France.

Set assistant Rutler befriended Aguilera while she shot Burlesque; they reconnected after her September split from husband Jordan Bratman. She and Bratman, 33 were married for five years and have a son, Max.

Rutler has been "really for her and is helping her through this difficult time," a pal recently told Us Magazine.

How does the star feel about turning 30? "It's better than turning 20, I'll tell you that," she told Ellen DeGeneres last month. "You're more comfortable in your own skin as a woman. You have a better idea of what you want and how to get it. At this time in my life, it's a huge turning point, it's a transitional stage and I'm ready. I'm ready."

Christina Aguilera's 30th Birthday in French Alps

Christina Aguilera celebrated her 30th birthday in the French Alps this weekend with a mix of pleasure and a little business.

Topping off a weeklong jaunt across Europe, the singer and boyfriend Matt Rutler flew on Saturday from Berlin to the posh French ski resort of Courchevel.

There, they immediately headed out in a two-horse-drawn sleigh, with glasses of wine in hand – white for her, red for him – as they took in the chalet sights and views on a ride around the village, an eyewitness tells PEOPLE.

Afterward, they returned to the luxury hotel Le Lana before Christina headed over to Les Caves disco, where she had a special singing engagement – performing a late-night set as the surprise guest at Ukranian industrialist Victor Pinchuk's 50th birthday party, which also included a special performance of Cirque du Soleil.

It's been a whirlwind week for the lovebirds, who hit a London nightspot, a Paris strip club and Berlin's elegant Christmas Market along the way.
