Rebecca Lobie serves up some serious underwear in a dazzling fluorescent yellow bikini

She rose to fame on social media as the “hot niece” of late environmentalist Steve Irwin.

And on Tuesday, Rebecca Lobie revealed why she managed to amass 118,000 followers.

The busty 32-year-old shared another racy image on Instagram, this time flaunting her curves in a bold fluorescent yellow bikini with minimal coverage.

“ Ok, yeah, so cute, ” the mother-of-two wrote.

In the image, Rebecca is seen giving a sultry look as she plays with her hair and poses in front of a mirror.

Her tie-front bikini top reveals a generous portion of the underside, while the bottom sits high on her hips.

Rebecca’s latest sultry bikini photo follows her equally cheeky post on October 12 where she got tanned in a sexy red swimsuit on a Sunshine Coast beach.

In the picture, she showed off her cleavage and a glimpse of her behind.

Her post also follows reports that Rebecca was hoping to ‘get well’ with her cousin Bindi Irwin.

The two women are rumored to have separated in the five years since Rebecca stepped down as CEO of Australia Zoo in 2015.

But there may still be hope for their strained relationship, with Women’s Day reporting that Bindi’s pregnancy may be the catalyst that brings them together.

According to a “ close family friend, ” Rebecca wants to “ make amends ” with 22-year-old Bindi and her 16-year-old brother Robert Jr.

“ Bec is resigned to not having an Aunt Terri in their life, but is desperate to at least make things right with Bindi and Robert before their grandfather is gone, ” the source said.
