Sorry Guys, Hayden's Taken!

She's TV's hottest cheerleader since Kelly Kapowski -- so it should come as no surprise that Hayden Panettiere has her own hero for Valentine's Day.

When asked about her V-Day plans as she arrived for a taping of "Live with Regis and Kelly," Hayden revealed she'll celebrate with her boyfriend, "Laguna Beach" stud Stephen Coletti. After the indestructible beauty broke the hearts of cameramen (and a few TMZ staffers) with her revelation, Hayden blew a kiss goodbye and disappeared.

FYI -- Valentine's Day is tomorrow -- and think twice before buying that cheerleader uniform for your girlfriend.
