Brooke and Alex's romance is set to be the steamiest in Bachelor In Paradise. But Bill isn't letting the women's connection get in the way of his plans to win over single mum Alex.
After Bill and Alex's double date in Fiji last week – which they shared with Brooke and Nathan – Bill says he believes there's "something special there".
"When we had one-on-one time to be able to talk about whatever we wanted, that was a really important step for us to work out that we did sort of like each other," Bill, 31, tells TV WEEK. "She's very charming."
And as Alex and Brooke's relationship heats up, plumber Bill admits he's not threatened by the pair's connection.
"It's something Alex definitely needed to explore," he says. "Otherwise, it would have been an unanswered question for her.
"I wasn't too worried, to be honest. I knew that me and Alex had been getting along well and that those two wanted to get to know each other."
In fact, Bill declares he's not going to get in the way of Alex and Brooke at all.
"I'm never going to tell anyone to back off," he says. "Who am I to stand in the way of someone potentially falling in love and creating a life together, all because I'm selfish and say I want them for me?
"Brooke and Alex needed to happen and it was good that something did."
And while Alex tells TV WEEK she really likes Bill, saying, "He looks like a Ken Doll and I really like his personality too," she can't deny her feelings for Brooke.
"This young woman is so smart and beautiful," she enthuses. "She has her head screwed on and she knows what she wants in life. There was just something about her.
"Oh, Brooke… be still my beating heart."
Bachelor In Paradise airs Tuesday to Thursday, 7:30pm, on 10.
