Sam Frost has a warning for the contestants trying to win Richie Strahan's heart.

Women across the country are losing their collective minds over the announcement of former The Bachelorette contestant Richie Strahan as the new Bachelor.

But former Bachelorette Sam Frost has issued a warning ahead of Strahan’s appearance on the popular reality show.

Frost, who has always been open about her affection for Bachelorette runner-up Strahan, launched into an on-air tirade this morning telling female contestants they’d better treat him right.

Speaking on her 104.1 2Day FM breakfast radio show alongside Rove McManus, 26-year-old Frost warned prospective love interests they’d better be applying for the show for the right reasons.

“If you want to get your claws into Richie, you better not be one of those opportunists,” Sam warned.

“You better be doing it for the right reasons. You better be doing it because you think, ‘You know what, I really want to fall in love’.”

“Because guess what, when you’ve done your little radio interviews like every Bachelorette does, when you come into the little S Fro studio, I’m going to grill you,” she continued.

“I’m going to make sure that you are doing it for the right reasons, you actually genuinely like him and you’re not just doing it to try and benefit off it, boost your profile.”

Despite her protective streak, Frost heartily welcomed Channel Ten’s decision to appoint 31-year-old Strahan as the new Bachelor, gushing: “He’s so fantastic. I’m so excited by this news.”

She even said she’d had a hand in the decision.

“I pushed for him to become The Bachelor to the producers but they wouldn’t tell me because they know that I get a little bit excited and I probably wouldn’t keep it to myself but I am really excited because he is so lovely,” she said. “I think it’s a really great thing and I think he’s going to be an incredible Bachelor.”

Frost, who chose handsome building construction manager Sasha Mielcarek as her main main in the Bachelorette finale last year, is living separately from Mielcarek because of work: Frost lives in Sydney for her radio show, while Mielczarek is based on NSW’s South Coast.

While Frost said in December she didn’t want to put pressure on the relationship, the coupe’s happy snaps on Instagram make clear the two are madly in love. 

Here’s hoping Strahan ends up just as happily matched.
