Billie and Sam joined Jessica Wright, Ferne McCann, Gemma Collins and Danielle Armstrong for a girls' day out and it looks like they had a fab time.
Expectant mum Billie, who has recently got engaged to her boyfriend Greg Shepherd, was pictured alongside Sam and Jess as they huddled together in white bathrobes.
Sam shared the picture on Twitter, telling her followers: "My beauties for a lovely relaxing Sunday xxx."
It's great to see Sam looking so well following her Crohn's Disease diagnosis and no doubt a day at the spa did her good.
Meanwhile, the TOWIE ladies also filmed themselves singing along to the song 'He Had It Coming' from the hit musical Chicago.
In a funny Instagram video, the girls are all lined up in their robes while laid out on loungers before suddenly sitting up and breaking into song.
Watch the video below, but be warned, Gemma's lyrics do contain swearing!
On Saturday night, Sam joined Ferne and Billie at a Beyoncé concert. Sounds like a perfect weekend to us!
Can we come along next time, girls?
