The fan wrote back: "I'm so sorry that happened to you".
She also shared link to a video from an interview she did about the incident.
The alleged incident made headlines after Affleck spoke out against Harvey Weinstein, who has been accused of sexual misconduct by several high-profile women in Hollywood, including Ashley Judd, Angelina Jolie and Gwyneth Paltrow.
Affleck, who starred in Weinstein's "Good Will Hunting" in 1997, said in his statement Tuesday the allegations against the prominent film producer made him sick. "We need to do better at protecting our sisters, friends, co-workers and daughters".
But now, many people are slamming Ben as well for his seemingly insincere statement.
He's always been touted as one of Harvey Weinstein's original protegees and now Ben Affleck's own questionable behaviour has come to light.
Burton, now a star on Lethal Weapon, replied, "Seriously, thanks for that".More news: Future crossover between 'The Walking Dead' & 'Fear The Walking Dead' confirmed — NYCC
During the interview, the actor seemed to be using his Hollywood A-lister status to make inappropriate advances towards Losique. She says her heart breaks for all the women who have suffered because of his "unforgivable" actions.
It comes after the 45-year-old had responded to the sexual harassment claims against film producer Harvey Weinstein.
McGowan confirmed to the NY Times that she was referring to telling Affleck about what Weinstein did to her.
"McGowan had promptly accused Affleck of lying, tweeting at him, "'I TOLD HIM TO STOP DOING THAT' you said that to my face. Affleck said. "I look like I have cerebral palsy now". But, I can tell you that I've never seen any of this behavior ever. While squeezing her, he says viewers would like the show more if she did it topless and asks why she is not showing more cleavage, among other sexual remarks. We see you, ' adding a heart emoji'.
Other actors, including Seth Rogen and Mark Ruffalo also addressed the situation in tweets we've gathered below.
Unlike Burton, Losique has bragged about the encounter in the past.
