Alex rose to fame when she won Richie Strahan's heart back in 2016 when she starred on The Bachelor.
The couple dated for a year but following their break up were reunited on the second season of Bachelor in Paradise and later revealed that producers tricked her into coming on the show.
"They actually told me that Richie declined three times. But, apparently, 48 hours before flying out to Fiji he [changed his mind]," she told 90.9 Sea FM’s Heather, Dan and Ben in April last year.
"It is disappointing and I can only trust that it was a 48-hour turnaround. But I suppose at the end of the day they’re trying to make a TV show."
The former reality star has also been romantically linked to AFL player Maegan Luxa, whom she was briefly engaged to as well as Bill Goldsmith, who she met during BIP.
“We came back from Paradise and it was good for three weeks and then he told me he didn't love me and I suppose we couldn't be together...,” she revealed at the 2019 finale.
“He just became really distant. The Bill I knew in Paradise isn’t the Bill I knew outside of Paradise,” she continued.
“I don’t wanna speak about him when he’s not here. I don’t wanna go into anything when he’s not here to defend himself”.
Alex also shares her 10-year-old son Elijah with her former boss.
