Dushku sent a warning message to The Bachelor star Girardi via Twitter.com on Tuesday (18May10), posting a screen grab of the reality star glancing at the former basketball player during a taping of Dancing with the Stars.
She wrote, "Vienna, I will CUT you. Keep yo' eyes on yo' own meat!"
But the Bring It On star has offered up an apology to Girardi, who is engaged to marry Jake Pavelka - in a bid to prove the comment was a joke.
Dushku tweets: "I heart the Pavelka's. I will fresh cut some flowers for Vienna in the a.m. and apologize if I hurt feelings!"
