Ben Affleck has apologised over accusations he groped an actress during a live music show when she was 21.

The actor wrote on Twitter: I acted inappropriately toward Ms. Burton and I sincerely apologize.

Affleck was apparently referring to his appearance on MTV show Total Request Live in 2003, presented by Hilarie Burton.

It comes after the 45-year-old had responded to the sexual harassment claims against film producer Harvey Weinstein.

The actor worked with Weinstein on Good Will Hunting, the Oscar-winning film which made the actor a household name.

Affleck tweeted that the allegations made him sick.

One Twitter user then commented that Affleck should’ve just kept quiet, and another wrote: He also grabbed Hilarie Burton’s breasts on TRL once. Everyone forgot though.

Burton then replied directly to the comment: I didn’t forget.

She then posted a video of outtakes from the show in which she appears to describe Affleck tweaking her chest during her interview with him.

Apparently talking about Affleck, Burton says: He comes over and tweaks my left boob, demonstrating someone squeezing her chest as she talks to the camera.

A few seconds later in the sequence Affleck asks her: How old are you, 19?

Burton, who acted in US teen series One Tree Hill, says she was 21 at the time.

She captioned her tweet containing the video: Girls. I’m so impressed with you brave ones. I had to laugh back then so I wouldn’t cry.

On Tuesday, actress Rose McGowan branded Affleck a liar over his statement condemning Weinstein’s unacceptable actions, claiming he already knew about the allegations.

McGowan says she was assaulted by Weinstein in a hotel room during the Sundance Film Festival in 1997.
