'RHONJ' Star Siggy Flicker Denies Allegations She Was at Capitol Riots

Former "Real Housewives of New Jersey" star Siggy Flicker is calling BS on the internet sleuths who say she was at the Capitol riots ... and she's got an alibi.

Siggy tells TMZ ... she was never near the Capitol during last week's attempted coup, despite some social media users claiming she was there. She says she wasn't even in D.C.

SF claims she's been holed up with her family at their home in Boca Raton, FL for the last 2 months and she was at the Boca Hotel and Resort with her kids and husband while the mob was busy storming the Capitol.

Siggy's on the defense because actress Vivicca Whitsett sent a tweet to the FBI, alleging Siggy is the woman wearing a MAGA beanie in this grainy picture from inside the Capitol. Siggy tells us the tweet is a "blatant lie."

Siggy also posted video of a Jan. 5 flight to D.C. showing a plane full of people singing "The Star-Spangled Banner," which seems to have gotten the ball rolling on the allegations ... but she tells us it's not her video, and she downloaded it from Twitter and reposted it on her IG because she thought it was "beautiful."

A diehard Trump supporter, Siggy tells us she last went to a Trump rally Oct. 16 in Ocala, FL and she doesn't support or condone the violence ... she says anyone who caused damage inside the Capitol during the insurrection should go to jail, no matter their political beliefs.

Siggy says she wouldn't be caught dead at a mass gathering like the Capitol riots because she's gearing up for another surgical procedure on her ankle and isn't supposed to be around large crowds.
