Republican presidential hopeful Donald Trump was accused Thursday of yet another incident of sexual misconduct, with former Miss Finland Ninni Laaksonen claiming that he "grabbed my butt" just before a joint television appearance in 2006.

According to Laaksonen, who was quoted in the "Ilta-Sanomat" tabloid, the incident occurred just before going on air on the Late Show with David Letterman alongside Trump and three other beauty pageant contestants.

"Before the show we were photographed outside the building," recalled Laaksonen. "Trump stood next to me and suddenly he squeezed my butt. He really grabbed my butt. I don't think anybody saw it but I flinched and thought, 'What is happening?'"

Former miss Finland did not come forward on her own, but spoke to "Ilta-Sanomat" as the tabloid conducted a round of interviews with Finnish women who had encountered Trump.

"Somebody told me there that Trump liked me because I looked like Melania [Trump's wife] when she was younger," said Laaksonen. "It left me disgusted."

At least 11 women, not including Laaksonen, have accused Trump of making unwanted sexual advances, including groping or kissing, from the early 1980s to 2007, according to reports in various news outlets.

Trump has denied the women's allegations, calling them "totally and absolutely false" and has promised to sue the women after the election.
