Christina Aguilera opened up about her "heavy" experience watching Surviving R. Kelly

Christina Aguilera had a difficult time watching Surviving R. Kelly.

“I was extremely moved by that whole show. It was very heavy for me,” the 38-year-old pop star told host Andy Cohen during Thursday’s episode of Watch What Happens Live.

“I actually went through a lot of,” she began, before getting choked up and telling Cohen, “let’s not really go there.”

Continuing she remarked, “But it absolutely did [touch me]. When you’re in this business, you’re so exposed to so many predators and so many things. Watching what happened to Aaliyah, and everything, you’re exposed to so much at such an early age.”

In 1994 it was widely reported that R. Kelly and Aaliyah had secretly gotten married and news outlets made public a marriage certificate that listed Aaliyah’s age as 18, though she would have been 15 at the time.

R. Kelly and Aaliyah never addressed the reports about the nature of their relationship, but in the documentary, his former personal assistant Demetrius Smith claims he was present at the wedding and admits to obtaining false documents for underaged Aaliyah.

Aguilera went on to address Lady Gaga’s decision to remove her 2013 recording duet with Kelly, “Do What U Want (With My Body), from all streaming services.

“I think she absolutely did the right thing. I love that she spoke and addressed it and showed her support,” the singer added.

Aguilera — who recorded a remix of the track with Gaga — also addressed how powerful it was to perform the track together during The Voice finale in 2013.

“Sharing the stage with her for that performance…it was almost like we were flipping it as one on the ear of everyone else,” she explained. “You can have this, you can have that, but you’ll never have my integrity, my voice. I was like, ‘Wow. It’s actually very fitting that we engaged together in this song having been in the business together as two females.’ ”

After the “Shallow” singer apologized in January for collaborating with Kelly in wake of his abuse allegations, Aguilera applauded Gaga’s decision to do the “right thing.”

“Cool to see the version of this song I did with @ladygaga on the charts again — this is a reminder of women sticking together— and not letting a man take ownership of a great song/ moment…And if anything the message of this song remains that although you may have had my body, you will never have my heart, my voice my life or my mind,” Aguilera wrote on Instagram, along with photos from their 2013 performance.

“Being a survivor of past predators myself, these lines spoke to me, which is why I did the song,” she continued. “I embrace all survivors of sexual and domestic violence and abuse holding a special place in my heart, and you @ladygaga, for doing the right thing! 💜”

Kelly, 52, has recently come under intense scrutiny in the wake of the Lifetime docuseries, Surviving R. Kelly, that features interviews with women who claim that for decades the hit-making singer and producer used his power and influence to sexually and physically abuse women and young girls.

R. Kelly’s lawyer has denied the allegations. In an interview with the Associated Press last month, Chicago-based attorney Steve Greenberg called the documentary “disgusting” and claimed that producers told “disgruntled” women incriminating things to say about Kelly off camera in an effort to incriminate the Grammy winner.

Producers of the film, however, denied the lawyer’s statement. “We are enormously proud of the series. The powerful stories from the women in the documentary speak for themselves,” they previously said in a statement to PEOPLE. “Their honesty and candor has resonated with millions of viewers.”
