Brielle Biermann Shows Off Glittering Diamond Engagement Ring While Posing in a Cheeky Knit Bikini

Brielle Biermann is taking her engagement bling poolside,

The 27-year-old reality TV star showed off her swim style — and her sparkling diamond ring — while soaking up the sun two months after getting engaged to minor league baseball player Billy Seidl, 24.

“Your best view 🧡," she captioned the Tuesday, April 23 Instagram carousel. The post featured snaps of Biermann and a mystery companion (presumably Seidl) sitting on lounge chairs next to a pool, the sunshine brightly shining.

Biermann sports a revealing pink and orange knit bikini with a triangle top and cheeky bottoms. The Don’t Be Tardy star’s hair is pulled back into a loose braid and she accessorized with gold bracelets. Her most noticeable piece of jewelry, however, is her sparkling diamond engagement ring. In one photo, Biermann shows off the bling by holding her hand up to her face to block her eyes from the sun.

The TV star previously shared a poolside selfie in which she’s wearing a pink one-piece suit, her diamond ring visible as she floats in the water. “Splashing the day away,” she captioned the March 18 post.

The couple announced their engagement in February 2024. Biermann shared a photo of Seidl down on one knee, which she captioned with, "Forever with you 🤍🥹🫀🫶🏻.”

They confirmed their relationship in April 2023 when Seidl posted an Instagram photo of Biermann sitting on his lap. "Whole lotta Rizz," he wrote in the caption.

Biermann gave fans a closer look at her engagement ring via her Instagram Story.

“It’s so shiny, I can’t stop staring at her,” she wrote over a photo of the round diamond ring set on a diamond band.

Her mother, Kim Zolciak Biermann, 45, shared another shot of the ring in a screenshot of a FaceTime call with Biermann after the engagement. In the Instagram post, Biermann flashes the ring while covering her smile with her hand. Kim is seen in the bottom corner, smiling while wearing black glasses and a black shirt.

She also shared a snap of Seidl down on one knee as well as a shot from Brielle’s point of view of the FaceTime call. 

“I’m so happy for @briellebiermann @bseidl21 nothing makes me happier than seeing my kids happy! 💍It’s the best feeling EVER!!,” the proud mom captioned the post. 

She added, “Love you both to the moon and back and look forward to alllll the years to come 🙏🏻❤️😍.”
