"Like most women in these situations I didn't say anything but I have thought a lot about what I'd say if I ever saw him again," she concluded.
Writer and comedian Jen Statsky, who is known for her work on Late Night With Jimmy Fallon, also tweeted about Tendler's allegations.
Tendler and Statsky's claims come just a day after Hilarie Burton accused Affleck of groping her breast on a 2003 episode of TRL.
Affleck then released an apology to Burton for acting "inappropriately".
On Tuesday, Affleck finally condemned Harvey Weinstein, who has been accused of multiple acts of sexual harrassment and sexual assault by several actresses.
However, TV host Anne-Marie Losique, whose 2004 interview with Ben Affleck recently went viral, claimed that she was not a victim of harassment.
"This was for the camera. You have to understand that we have done dozens and dozens of interviews like that. It was for a show I was producing, so I was not at all a victim," Losique told The Hollywood Reporter.
Losique said the interview was just an act and as soon as the cameras stopped "there was none of that".
"He never touched me in any improper way. He was very respectful," the Canadian host said, adding that she's not "thrilled" to have the interview mixed in with the sexual harassment allegations against Weinstein because she doesn't "think that is at all the same thing".
Affleck reportedly visited a rehab centre in Los Angeles on Wednesday.
