Ben Affleck has apologised for groping an MTV host's breast live on air, after he publicly condemned Hollywood producer Harvey Weinstein for allegedly sexually harassing dozens of women.
The actor appeared on MTV's music video show Total Request Live in 2003, and footage appears to show Affleck touching co-host Hilarie Burton's breast.
Video of the incident re-emerged this week after Affleck denounced Weinstein on Twitter.
On Wednesday Affleck tweeted an apology, saying he "acted inappropriately toward Ms Burton".
Burton has tweeted her support for Weinstein's victims, and said that during the incident with Affleck she "had to laugh … so she wouldn't cry".
Her tweet was in response to a fan, @ShaniceBrim, who said Affleck "grabbed Hilarie Burton's breasts on TRL once. Everyone forgot though".
Burton responded: "I didn't forget."
Alleged Weinstein victim Rose McGowan has hit out at Affleck, accusing him of lying after he claimed he did not know about Weinstein's behaviour.
McGowan wrote on Twitter: "GODDAMNIT! I TOLD HIM TO STOP DOING THAT' you said that to my face. The press conf I was made to go to after assault. You lie."
Affleck said on Tuesday he was "saddened and angry" to hear about the allegations against Weinstein.
In October last year, Affleck criticised then-presidential nominee Donald Trump for lewd comments he made about women in 2005, which Mr Trump had dismissed as "locker-room talk".
Speaking to Vanity Fair, Affleck said: "Women should never be talked about in that way. Even if it was a private conversation."
But in another video that's re-emerged in recent days, Affleck is seen touching reporter Anne-Marie Losique's breasts and suggesting she film a show topless.
The reporter, who was on Montreal entertainment news show Box Office, sat on Affleck's lap during the 2004 interview.
Affleck, who can be heard slurring his words, said: "You usually show a lot more cleavage than this. What's the story? Why are you covering up today?"
He later added: "These breasts are really firm, suspiciously firm."
Losique told Variety this week that she and Affleck were "just mugging for the cameras".
She added Affleck never made any off-camera advances towards her.
