For example, plenty of people would reject a friend's ex faster than you can say "ghosted." However, not everyone is against going out with someone who previously dated someone close to them - even if that person is family! Here are 13 celebs who reportedly dated or hooked up with a family member's ex: 1. While Travis Barker was dating Paris Hilton in 2006, he was also crushing on her friend and closet organizer, Kim Kardashian. His on-and-off relationship with Paris was brief, and the next year, he reportedly had a short relationship with Kim.

You might think I would be doing the worst things with this girl because of her tapes, but it was the exact opposite of any other encounter I've had with a woman: With Kim, I wanted to be nothing but a gentleman to her. It was so weird... We'd be really sweet around each other, like little kids, and then when we were apart, she'd call me and say, 'I want to see you again.' 'Me, too,' I'd say."

After they made their relationship public, some fans brought up his past with Kim. Raymond Hall / GC Images / Via Getty He told the LA Times, "It's like, 'Kourtney's fans are worried about Travis. He's a womanizer.' Stop it. I obviously shared all that stuff [in my memoir] because I wanted to move past it. It was therapeutic for me... That's her sister. She knows we used to talk. Nothing bad was going on. You give people a little information, and they think they've solved the mystery of 'this is why they're fighting.' It's just so ridiculous."

But he dated Paris, and we were all friends, and we'd all hang out, and when I was with Paris, we'd be on the road and go to their tour in Amsterdam. So I have been friends with him, but never in that way. And never hooked up with him... Kourtney was around during that time; they were neighbors for a decade. He was always around with his kids; they'd always come to Kourtney's house for the birthdays. So, everything was super open and cool. Everyone's been friends. He was just as good of friends with them as he was with all of us. So, it was nothing weird." Steve Granitz / FilmMagic / Via Getty Travis and Kourtney got married in 2022.

In 2023, Tish Cyrus married Prison Break actor Dominic Purcell, who - according to People - was reportedly "seeing" Noah Cyrus, Tish's youngest daughter, "in a friends with benefits way, off and on."

The source said, "They stopped seeing each other, and then Tish started something up. Tish knew he had been seeing Noah... Tish never gave Noah the chance to talk about all of this before they got married."

Noah and her older brother, Braison, didn't attend Tish and Dominic's wedding. Michael Kovac / Getty Images for John Varvatos 3. In 2013, Demi Moore reportedly dated restaurateur Harry Morton for six months. At the time, a source told E! News, "After dating for six months or so, they both realized that while they had become very good friends through the dating process, this wasn't going to turn into a long-term romance... They quietly stopped having dates together, but they have remained in regular contact as they get on so well. You will occasionally see them together as friends but they have stopped seeing each other romantically."

A source told E! News that Harry actually introduced the pair. JB Lacroix / WireImage / Via Getty, Alberto E. Rodriguez / Getty Images 4.
