The TOWIE star, 26, ignored the April showers when she stayed indoors in the warm and showed off her AMAZING body in a bikini (and heels natch).
The reality TV star and boutique owner showed off a strappy neon bikini from her new range at InTheStyle.com.
I mean, who better to advertise her own range than herself? Especially with a body like THAT.
In the photo, mum-of-one (yes, really) flaunted her toned abs in the gorgeous neon coral two-piece, which will soon be available online.
Billie wrote: "Love this bikini I designed with @inthestyleuk - fits perfect!"
Quite rightly, her combined 2.41million Twitter and Instagram followers described Billie as "sexy", "beautiful" and "fantastic".
Another said: "Why can't I look like this?"
A second simply "loved the colour".
Yep, us too!
Billie launched her first clothing range with InTheStyle.com last November, with her swimwear collection coming out this month.
She recently looked ethereal at the In The Style collection launch, alongside fellow reality TV stars Charlotte Crosby and Binky Felstead who were also unveiling their new season collections.
Billie is currently starring in the 17th series of The Only Way Is Essex on ITVBe.
