Not only is the former TOWIE star in sun-drenched Dubai, she's also got a body to die for - just four months after giving birth to her first child!
After she posted a picture of herself in a floral bikini holding cute tot Arlo in her arms (Sunday 11 October), we weren't the only ones to notice how amazing she looks!
Fans gushed messages, including: "How is it possible to look this good so soon after having a baby?!"
Another said: "She is like the hottest momma to have lived."
Others quickly commented on Billi's exercise regime, including yoga and cycling.
The day before, yoga instructor Billi had told her 315,000 Instagram followers that she was about to embark on her first family holiday as a threesome.
Obviously flying first class - we wish! - she later shared a picture of fiancé Andy Carroll and baby Arlo making themselves comfortable on the flight - with little room for mummy!
She joked: "Looks Like Mummy Sitting On the Floor."
Proud mummy also shared pictures of her adorable son Arlo enjoying his first swim in a hotel pool.
The couple appear to be staying at the luxury Al Qasr Hotel, Madinat Jumeirah, where Billi told fans she was enjoying 'Arabian nights'.
Sharing a picture of herself in a gorgeous berry kimono-style dress, once again Billi looked absolutely fabulous.
