The 36-year-old star appeared on Joan River's web show, In Bed With Joan, on Tuesday where he talked about the ways in which Orange Is the New Black has changed his life while also throwing some serious shade at the 38-year-old blonde.
During a segment called "Live or Die," Biggs was asked to choose between Reid and Lindsay Lohan, and he didn't hesitant before dissing (and ditching) the Sharknado star.
"Lindsay Lohan stays," the new dad replied (head to the 12:39 mark to watch).
As for his reason behind keeping Lohan alive?
"Well, she's got nice boobs, she really does. Lindsay's got nice boobs," he candidly shared before criticizing Reid. "Tara's body—I don't know what's going on with it. I don't think she ever knows what's going on with it."
"And Lindsay does?" Joan replied.
"Lindsay doesn't know what's going on with Tara's body either," he said. "No one knows what's going on with Tara's body."
This isn't the first time Biggs has taken a jab at his former American Pie costar.
During an appearance last year on Watch What Happens Live, the Orange Is the New Black star was asked to pick Reid's prison nickname.
His response? "Hot mess."
Well, that didn't go over to well with the Big Lebowski beauty, who took to Twitter after the diss to reveal her disappointment.
"@JasonBiggs it's really sad I just landed in LA and the first thing I read about you that you are calling me a hot mess.i I've supported u !," she wrote.
To which he replied: "@TaraReid I love u Tara, it was a joke! Didnt mean to offend, Totally kidding around! it was a game! Xoxoxo"
Reid has yet to respond to Bigg's latest slam, although it's safe to predict she isn't too pleased.
