Jason Priestley had to cut off some of his "jealous" friends when he found fame.
The Beverly Hills, 90210 star - who portrayed Brandon Walsh in the series - expected to have several "ride or die bros" throughout his life, but he had to de-friend some because he didn't like how they were acting towards him.
Speaking on the Still Here Hollywood podcast, he said: "I had a few friends that had been my friends for quite some time.
"Even before I moved to Los Angeles, I started to recognise behaviour in them that wasn’t anything I wanted to be around anymore.
"I actually had to cut a lot of people out of my life.
"I didn’t have that many friends anyway, but a handful of guys that I thought were going to be my ride or die bros forever."
Jason recalled facing some "undercut" behaviour from his so-called friends.
He added: "Things happen, especially when you’re young like that, and people get jealous.
"And then people start to do things to undercut."
Jason found it is "usually girls who do that", so he was "surprised" by what happened with his male pals.
The actor also admitted he was "super thankful" he reconnected with his Beverly Hills, 90210 co-star Shannen Doherty before she died in 2024, aged 53.
A month after her passing, Jason told how he started to "think about his own mortality".
Speaking to the Sunday Mirror newspaper, he said: "It has made me think about my own mortality. I woke up on my 50th birthday and I realised that I’d already lived most of my life. Her passing hit me hard. We had an incredible experience working together... it was the day Shannen, Luke [Perry] and I were shot for the cover of Rolling Stone [in 1992] that I started to understand the impact the show was having."
The former Private Eyes star remembered Shannen as being "very open" about her health battles and commended the Charmed star - who spoke candidly about her illness through her Let's Be Clear podcast - for her determination to help others as he admitted he felt "very fortunate" to have been able to spend time with her in those last moments.
