Hailey Bieber is sure to put on plenty of sizzling beach displays this summer. 

And on Sunday, she whiled away some time while self-isolating with husband Justin Bieber  by promoting her latest Roxy swimsuit collection on social media. 

The 23-year-old posed in a black one-piece with neon green stripes from her Sister collection with pro surfer pal Kelia Moniz.

Moniz, 27, was seen in a neon green bathing suit top and white high-waisted short shorts, featuring the neon green stripes down the sides and matching laces.

Moniz also shared some photos from the campaign, one featuring an aerial shot of her swimming in a pool while Bieber walked past in a neon green one-piece.

Another showed Bieber wearing a white RXY hoodie and white bikini bottoms while Moniz rocked an oversized black t-shirt with cut-off blue jean shorts.

They were photographed for the campaign by Moniz’s husband Joe Termini, who introduced the gal pals.

This marks the pair’s third of four Sister collections with Roxy, having launched the first last March and the second in July.

Bieber told Cosmo about how their friendship inspired the swimsuit collection last March when the first collection dropped.

She said: ‘We’re just close. We got along really easily from the day we met. It sounds like we’re like a couple. [laughs]

‘I guess for a minute, it felt like we were, because I was single and alone and attached to Kelia’s side, and she’s a married woman.’
