Christina Aguilera strips down to cowboy hat as she drinks huge bottle of Champagne in bubble bath

Christina Aguilera recently served some body in a bikini for a poolside Christmas.

And the five-time Grammy winner was even more underdressed while ringing in the new year.

She stripped down to a cowboy hat Friday, as she polished off a huge bottle of Jay-Z’s Champagne brand Armand de Brignac, while soaking in 2021 with a New Year’s Day bubble bath.

The 40-year-old left little to the imagination, dancing around with her bubbly to some sexy smooth jazz in the Instagram video, which featured a vintage filter.

She popped the gold bottle, before posing with it in the tub, covering her busty chest with her arm and some suds.

Christina sat up and leaned over the edge of the black stone freestanding tub, pouring herself a glass. 

She also gave a glimpse at her beautiful spacious bathroom, which featured matching marble walls and black and white tiled floor.

The Burlesque star previously ordered up some fake snow for her poolside Christmas with fiancé Matthew Rutler, 35, and their children, posting a glimpse Monday on Instagram.

She wore a Minnie Mouse Santa hat with her swimsuit, as she puckered up to Rutler in the pool, writing: ‘holiday photo dump – stay home edition’ 

Christina shared a sweet photo of their daughter Summer Rain, six, passed out in her pajamas on the floor after opening presents. 

In another cute snap, she hugged her son Max Liron, 12, whom she shares with ex-husband Jordan Bratman, 43, to whom she was married from 2005 to 2011.

The Reflection artist posted a video of a man hosing their gated yard down with snow, for a white Christmas in Beverly Hills, complete with a bounce house.

She also shared a clip of their yellow lab pups Mowgli and Baloo running around and playing in what was likely their first snow. 

In addition to Christmas, she celebrated another trip around the sun last month with her milestone 40th birthday.

Christina wrote a touching note to her new age on Instagram, which included: ‘This ever-present social stigma exists around getting older, but I have ALWAYS embraced it! 

‘I am forever an old soul and I appreciate the wisdom, grace and beauty that comes with each new year of life. I treasure the growth that comes with age and I welcome the knowledge from the greats that came before me.’
