Are they sisters or mother and daughter?! We can't tell!

Model Bella Hadid and her mom Yolanda Foster struck a stunning pose while poolside on Sunday. The gals were clearly chanelling their inner Pam Anderson because those red-suited ladies totally look like Baywatch babes!

The 18-year-old "It" girl posted the pic on her Instagram account, along with the caption, "Mommy n meee day. Home is when I'm with you my [angel]."

Aww -- so sweet!

We're glad to see that the 51-year-old Real Housewives of Beverly Hills soaking up the sun since she's had a scary battle with Lyme disease since 2012. The gorgeous lady has chronicled her battle with the chronic illness -- at times being unable to get out of bed or read. We're happy to see that perhaps Yolanda is on the mend!

Meanwhile, Bella also went public with her budding romance with R&B singer The Weeknd (whose real name is Abel Tesfaye) on Sunday when she posted a photo of her older sister Gigi and the crooner with the caption, "My ❤️s" -- basically confirming the rumored relationship. Bikini pics and cementing her BF/GF status?! What a busy weekend for Bella and The Weeknd!

My ❤️s
