Christina Aguilera has been very vocal as she’s approached a big birthday milestone this past week and on Friday the big day came. The "Reflections" singer and former The Voice mentor hit the big 4-0 and celebrated with a series of posts talking about embracing her age… with a couple of middle fingers and a catsuit, of course.

In a series of posts over the weekend, Christina Aguilera shared details about what 40 means to her, both from a mental and a physical perspective. Her last look was at her badass birthday nails and she made no bones about throwing up her middle fingers on her birthday.

Christina Aguilera also shared a post with her fans explaining what turning 40 has meant to her. In fact, she seems to be pretty positive about the direction her life is going in as she hits the momentous milestone. She called herself “humbled” and “blessed” on her Instagram account, also revealing:

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.

Christina Aguilera has always been open and candid about empowering herself and for hoping to set herself up as a celebrity in a way that she can be a role model for other women to do the same thing. She noted around the time her movie Burlesque came out that there has always been a double standard when it comes to sexuality, telling CinemaBlend that she’s always wanted to champion empowerment ideas.

I knew going into this movie that that’s what burlesque means to me. I think it’s extremely empowering for a women to feel confident within her own body, within her own skin and to not be afraid of being fearless about that. I think that there are a lot of double standards, people can judge, but at the end of the day this is a movement and it’s a powerful expression and it’s a way that women can empower themselves and feel good.

As part of her 40th birthday celebration, she also took to social media to show off a brand new look in a catsuit, confidently showing off her curve-hugging look while strutting to a Megan Thee Stallion track. Anyone who can capably rock those heels at 40, much less a catsuit, should be feeling pretty good about themselves.

It’s been a big year for 40th birthday celebrations. Recently, Kim Kardashian also went all out for her 40th birthday, in her case sharing an epic bikini pic and images from a private trip with some of her nearest and dearest friends and family. While Christina Aguilera doesn’t seem to have celebrated on a private island, it looks like she had the best time nonetheless.

Meanwhile, Christina Aguilera isn’t the only singer from her era to be close to or reaching 40. Britney Spears just turned 39 earlier this month and Justin Timberlake will turn 40 in January. Nick Carter already hit his 40th birthday back in January of this year. I guess these days the former pop stars are all kissing their youths bye bye bye.
