Selena rang in 31 years with a star-studded event.

She simply captioned her Instagram party post: “31.”

The first photo featured Selena in a tiny red, leather dress, which showed off her ample cleavage.

It also came way above her thigh and was decorated with red flower petals and strings.

The Only Murders in the Building star leaned against a wall on a stairway to try and balance on black, laced-up heels.

The back of the heels had the same petals that were on her dress.

She wore her hair in an updo, with a piece of her bangs hanging down.

Selena shared more photos of her special day, which featured a big white and red cake, a DJ, and dancing with her friends.

Some of the guests included Paris Hilton, Christina Aguilera, and more.

Her best friend, Taylor Swift, was not in attendance, as she performed at The Eras Tour in Seattle, Washington, that night.

Selena posed with her friends in her strapless dress and showed off major sideboob.

The singer added black sunglasses and someone’s suits jacket to her look.

‘THANKFUL’

Earlier in the day, Selena wore a much more modest outfit to thank everyone for their birthday wishes.

“I am thankful for so much in my life and one of the things I am most thankful for is the work we’ve been able to do with the Rare Impact Fund through @Rarebeauty,” she captioned the post.

“Because of YOU we’ve been able to raise awareness and increase access to mental health services for young people. This is my true passion in life. People keep asking me what I want for my birthday, and I tell everyone the same thing please do not get me anything but if you want to do something for my birthday, please donate to the Rare Impact Fund.”

She ended with, “If you have the means, consider donating to help us make a difference.

I LOVE YOU ALL!

The 31-year-old wore shorts shorts and a pink t-shirt as she blew out her candles on a floral cake.

Her long, blonde hair fell onto her shoulders and she wore natural make-up.

SEXY SELENA

Selena showed off her curves earlier this month in a tiny bathing suit.

She posted summer snaps of her and her friends while posing in a textured bathing suit.

The Instagram post included four shots of the Rare Beauty founder lounging by the pool with touseled hair and no makeup on.

In the third photo, Selena was seen in a brown, one-piece thong bathing suit that showed off her upper thigh as she posed on an outdoor couch next to Nicola Peltz Beckham.

The next snap showed the Disney Channel star smiling from inside the pool as she stood with her arms folded over the siding.

Shortly after, Selena took to her feed again with more summer snaps – this time including her pal Taylor.

Selena and Taylor have been best friends for years, and Selena’s post showed the two showing off their relationship even further.

She uploaded four different Polaroid shots, with the bottom two showing Taylor hugging Selena from behind and the two sharing a red, white, and blue Firecracker ice pop.

Selena rocked a simple white T-shirt and two braids in her hair while the All Too Well hitmaker sported a floral yellow dress.

“Sometimes you need to be around empowering, kind and kick a** gals. I needed that,” Selena wrote in the caption.
