The Bachelor's Alex on her "game changing" talk with Richie.

She’s the hot favourite to win Bachelor Richie’s heart on this year’s season of the Channel 10 dating show, but Alex Nation has revealed she has a “game-changing” chat with Richie this week.

Rosie recaps The Bachelor Episode 1: Dickie Bach is the Aussiest Bachie Bloke of them all.

Speaking to TV Week magazine, the 24-year-old said she’s laid out all the cards for Richie when it comes to her life as a single mum.

"I think he felt the full gravity of me being a mum, because I spoke about it in depth. I could see he was trying to process it all. It was pretty overwhelming for him," she told the magazine.

"It definitely changed the dynamic between us. It was like I’d laid out all the cards and said, ‘this is my life, this is my child and this is what I’m all about.’ He went away from our talk with some pretty big things to think about."
