Justin Bieber’s step-sister, Allie Bieber, is always supporting her sister in law.
Allie, 18, took to Instagram on Thursday, August 7, to show off her Rhode products. In the reel, she waved her Rhode Peptide Lip Treatment to the camera before unscrewing it and applying it to her pout. Allie gave the camera a kiss while showing off her hydrated lips.
Allie teamed her soft glam with a white tank top featuring a scoop neck and a fitted, cropped fit. She styled the basic with striped boxer shorts and white cowgirl boots.
Allie tagged Hailey Bieber in her story, leading the Rhode founder to repost it.

Throughout the years, Hailey, 28, has shared lots of sweet moments with Justin’s sisters. (Justin is the son of Jeremy Bieber, and Pattie Mallette. He has three other half siblings: Jazmyn, 17, and Jaxon, 15, who Jeremy shares with Erin Wagner, and Bay, 6, who Jeremy shares with his current wife, Chelsey Bieber. Chelsey welcomed Allie with a previous relationship.)
When Jazmyn saw Hailey in her wedding dress for the first time in September 2019, she gasped and gushed in a YouTube video documenting the couple’s nuptials, “Oh my gosh! You look so pretty.” Allie added, “It’s so pretty!”
They’ve also made dancing videos together on TikTok, and Hailey was seen playing with them at a baby shower and taking pictures together.
Justin, 31, has praised Hailey and his sisters on multiple occasions. In December 2021, he snapped a black-and-white selfie of himself, Hailey, Allie and Jazmyn hanging out. “My favorite girlsss 
,” he captioned the post.
Allie returned the love by commenting, “Love you.”
