While most Housewives and viewers were in the comfort of their own home anxiously awaiting the premiere of last night's part one of the Real Housewives of Beverly Hills reunion, Lisa Rinna was getting some major R&R in paradise.

How to Watch

Watch The Real Housewives of Beverly Hills on Peacock and the Bravo App.

And she's been seriously strutting her bikini body! The mother of two has been teasing us with pics of her vacay for the past week, and aside from being jealous of the beyond beautiful locale, it's her fierce figure that's truly enviable. (Can you believe she's 51 years old?!)

Another day in paradise. ðð´

She also looked flawless in an electric blue one-piece, holding hands with her daughters while walking along the shore.

One fan, though referencing Lisa's hot bod, thought it was a great "Mom moment" to tone things down a little and let her daughters take the spotlight. "I love that you put on a one piece and let your girls shine," she commented on the pic. "Shows so much character because your body is so hot but you know what's important."

My loves.

Aside from spending quality time with her girls and enjoying some serious spa time, Lisa also celebrated 18 years with hubby Harry Hamlin, posting a super cute throwback of the two on their wedding day. So presh!
