NEW YORK - Tera Patrick has taped a special Valentine's Day appearance on the NBC late-night talk show "Last Call With Carson Daly." The Feb. 14 broadcast will feature Patrick's Mistress Couture lingerie line.

According to Teravision publicist April Storm, Tera is introduced on the show as "the number-one porn star in the world." She then shows off her Mistress Couture fashions and sings a rendition of the "Grease" soundtrack staple "Hopelessly Devoted To You."

"It's Valentine's, a day for romance," said Tera. "And what better way to celebrate than with sexy lingerie and show tunes?"
