Singer Lady Gaga will be joining Piers Morgan to discuss her experience with post-traumatic stress disorder.

Vulture reported that Gaga and Morgan had a Twitter exchange about her experience with PTSD. The conversation appears to have started when Gaga tweeted a message of support to Madonna after her Billboard Music Awards speech in which she spoke about misogyny and sexism in the music industry.

The Twitter conversation also followed Morgan's tweet Saturday in which he wrote,"Lady Gaga and Madonna have both made allegations of rape many years after the event. No police complaint, no charges, no court case."

"I don't think all claims of rape should be necessarily accepted as fact without proper criminal investigation, do you?" Morgan said in reply to another Twitter user.

Two days later, Morgan tweeted, "I wouldn't automatically believe anything either Madonna or Lady Gaga claimed about their lives," in response to a different user.

On The Howard Stern show in 2014, Gaga alluded to being sexually assualted as a teen . She wrote an open letter Dec. 6  about her struggle with PTSD. She took issue with Morgan's comment about the lack of police reports on rape.

"I've worked with our vice president Joe Biden on helping educate people about why women don't report, would love to share it with you some time," she tweeted Tuesday.

"OK, you're on," Morgan wrote. "Let's do an interview about this and you can tell me why I'm wrong to be sceptical (sic)."
