Leah Costa is ‘dating former Big Brother star Anthony Drew’

Leah Costa dramatically left Bachelor In Paradise on Sunday night after discovering there would be no more male intruders.

But the 25-year-old looks to have the dating show far from her mind.

A source told Daily Mail Australia on Monday that the blonde is in a relationship with former Big Brother star and Tully Smyth’s ex Anthony Drew.

Leah’s mystery man REVEALED: Bachelor In Paradise star Costa is dating former Big Brother star and Tully Smyth’s ex Anthony Drew after her dramatic exit from reality show… but are they engaged?

‘Leah’s new boyfriend is Anthony Drew from the 2013 season of Big Brother and they could potentially be engaged,’ the insider exclusively revealed.

Daily Mail Australia has reached out to both Leah and Anthony for comment.

Following her exit from Bachelor In Paradise on Sunday night, Leah took to Instagram to reveal that she’s finally found her prince charming.

The star wrote: ‘I said I hoped that something bigger and better was waiting for me on the outside. I guess it’s true that when life appears to be falling to pieces, it is really just falling into place.

‘I never thought I could find a love like this,’ Leah concluded, adding a love heart emoji.     

It comes after Leah sparked engagement rumours by posing with a diamond sparkler on her wedding finger earlier this month.

In an Instagram Story shared to her page, the Channel Ten personality was seen flashing the eye-catching bling during what appeared to be a romantic evening at a drive-in cinema.

In a second snap shared to her Instagram Story, which saw pillows strewn about the back of the vehicle, Leah wrote: ‘Drive In… He Spoils Me,’ accompanied by a heart-eyed emoji.

She has since flashed the ring during appearances on Studio Ten and The Project.

Now working as an actor and model, Anthony became a household name back in 2013 thanks to a stint on reality series, Big Brother Australia.

The long-haired hunk quickly made headlines when he began a romance with co-star Tully Smyth in the house, while she was in a long-term relationship with Tahlia Farrant.

Tully’s girlfriend dumped her via social media while she remained oblivious in the house, and she continued her relationship with Drew after the elimination.

Their romance was short-lived however, with the couple splitting in January 2014.

Tully, 30, has since been romantically linked to other men, including former Bachelor star Richie Strahan.
