AJ McLean, who is best known for being a member of the 1990s band The Backstreet Boys, spoke out this week to throw his support behind Britney Spears.

While being interviewed on SiriusXM’s Andy Cohen Live on Wednesday, McLean described Spears’ conservatorship as “asinine,” “insane” and “completely brutal.”

“My thoughts and my prayers are with her. I am 100 percent team Britney,” McLean said emphatically.

McLean went on to say that Spears lives so close to him in Los Angeles that she is “pretty much my neighbor.” He added that he sees her “often” because they each frequent the same shopping center in their area.

“There’s this amazing cupcake shop that she goes through, that I go to,” he said.

McLean then recalled the last time he ran into Spears, saying that their interaction was heartbreaking for him.

“The last time I saw her, it broke my heart,” McLean explained. “Last time I saw her, she was with a gentleman. I’m assuming it was security or maybe a driver.”

McLean was at the cupcake shop because his wife had asked him to get some cupcakes for a birthday party for one of his daughter’s friends.

“Went in, she was there, she looked right at me and I was like, ‘Hey, it’s AJ,'” he remembered. “And she just kind of had this glass face. Like, she just didn’t know who was there. It took her a minute. And then she realized it was me, and we hugged and we talked for a brief moment, but I could just see that this wasn’t her. Like, I’m not looking at the person I knew from years and years ago.”

In this same interview, McLean revealed what he thinks about the other restrictions that Spears has been forced to endure under her conservatorship. He said that it “really grinds my gears” that Spears allegedly isn’t allowed to “stay in contact” with anyone from her AA meetings or fellowship.

This comes after Variety reported that Spears told a judge last month, “I have a friend that I used to do AA meetings with. I did AA for two years. I did three meetings a week. I’ve met a bunch of women there. And I’m not able to see my friends that live eight minutes away from me, which I find extremely strange.”

This hit home for McLean because he is part of a sobriety program as well.

“That is BS to me, because that’s the whole core of what we do in this program is fellowship,” he said. “We lean on each other, we look up to each other for support and… if somebody were to take that from me, it would really be difficult for me to stay sober, honest to god… I just wish [that] for her, honestly.”

McLean said that another thing that “really irks” him about the Spears situation is her not being allowed to have another child, as she claims she’s not allowed to remove her IUD to become pregnant again.

“That, to me, is physical abuse. Just the whole thing to me is just, it’s grotesque,” he said. “I really feel in my heart that she’s going to break free of all of this, and I really hope that she does. She’s a sweetheart.”
