Sam was struck down with a mystery illness during her time inside the Celebrity Big Brother house, and last week was admitted to hospital for treatment.
After being discharged from hospital earlier this week, Sam has been resting at her mum Sue's house in Essex.
It was only yesterday that Sam told fans how she couldn't wait to get out, and she finally got her wish with Billie this morning.
Captioning a photo of the pair, Sam said: "Yay, feels good to be out & about today @BillieFaiers #babymumma #sisters #auntie2be."
Sam also appeared to be relishing in home comforts again following her stint in the CBB house, as she enjoyed a Chinese takeaway last night too.
She told fans on Twitter: "Mmm 1st Chinese takeaway in over a month, this is going to be good x."
Sam certainly hasn't had an easy time over the past few weeks, but she's planning to cheer herself up in the coming months after booking a girlie holiday to Vegas with best friend and TOWIE co-star Ferne McCann.
Meanwhile Billie, who has just returned from a 'babymoon' in the Maldives with boyfriend Greg Shepherd, looked radiant as she joined Sam en-route to a photo shoot.
Reality star Billie confirmed last month that she and long-time boyfriend Greg are expecting their first child together this summer. She tweeted the happy news on 7 January, writing: "I am so happy to tell you all, that Greg and I are expecting our first baby! We are so excited!! Thank you for all of your kind messages."
