Rachel Bush In See-Through Undies Shows Her 'Birthday Behavior'

Rachel Bush was shouting out her "birthday behavior" as she sizzled in sheer undies for a celebratory Instagram update in November 2022. Marking turning one year older for her 4.1 million fans, the NFL wife showed off her killer curves as she posed in see-through underwear, even including her cake as she dropped a gallery of hot shots for her adoring followers. Dropping jaws with her ample assets as she also flaunted a mean set of abs, Rachel upped the ante in her sexy girly lingerie, but there was more to it as she switched to a racy black thong look as fans swiped.

Scroll for the photos. Offering up a cleavage flash as she rocked a push-up bra and matching briefs with coordinating suspenders, Rachel wowed as she went barely there in thin, sheer, lacy fabrics in lilac and green, although much of the cup area of her bra was totally see-through.

Hinting at her toned legs as she sat with her white birthday cake on her lap, Rachel rocked her bombshell brunette locks down as she delivered a very slight and sassy smile, then returning for an outdoor, waterfront shot as she struck a more casual pose with her cake next to her.

Flaunting her eye-popping curves in every photo as she also showed off her impressive abs, Rachel lost the girly vibes for a racier look further along in the gallery, this time posing for night-time snaps. Dropping it low in a black thong bodysuit and matching high heels, the wife to Buffalo Bills player Jordan Poyer cranked up the heat as she switched out her white cake for a red one, posing by a vehicle and eventually standing up to show off her sexy thigh-highs look.

"Birthday behavior," Rachel wrote in a cheeky caption as fans went wild in the comments. "PERFECT! BEAUTIFUL! SEXY!" one fan gushed. "Beautiful, babe," another told the mom of one.

Rachel lost the high-brow posing for a gorgeous, sunkissed snap in this photo, showing off her sensational curves in the tiniest of orange bikinis as she melted fans with her smile. Rocking her stringy swimsuit with seashell accents adding tropical vibes, Rachel wrote: "I think the iPhone camera quality is better than my actual eyesight."

Rachel has opened up about being a high-profile WAG. In 2018, she married Jordan, although it was prior to tying the knot that she admitted that dating an NFL player is "a lot of work."

Mentioning her daughter as she spoke to Sports Gossip, Rachel said: "Before having Aliyah it was a piece of cake. Besides the constant worrying about Jordan getting hurt or being alone when he traveled I was fine. Living my best life! Lol. Then when Aliyah came in the picture my whole world flipped upside down!"
