excited to be tonight on @CNNHeroes An All-Star TRIBUTE with @AndersonCooper.tune in as we honor inspirational heroes.
As usual, we've got a lot of star power joining CNN tonight to honor these Heroes.
We've got movie stars: Susan Sarandon, Maria Bello, Harvey Keitel (Mr. Wolf!), Viola Davis and Josh Duhamel.
We've got TV stars: Rainn Wilson, Jane Lynch, David Spade, Rico Rodriguez, Miranda Cosgrove.
We've got an Olympic gold medal swimmer (Cullen Jones) and a NASCAR legend (Jeff Gordon).
And then we've got two ridiculously talented musicians performing in Ne-Yo and "American Idol" winner Phillip Phillips. Should be a fun night.
Actress Holly Robinson Peete was just interviewed on the red carpet by CNN's Nischelle Turner. She called herself a CNN Heroes "groupie."
"The Heroes are walking past, and I'm just starstruck," Robinson Peete said.
The top 10 just made their way to the red carpet together. Picture coming up.
Anderson Cooper just stopped by the social suite, giving a little preview of what's to come when he hosts CNN Heroes - live in just under an hour.
Honored to be a presenter at #CNNHeroes All-Star Tribute TONIGHT. Tune in at 9pmET/6pmPT on #CNN to see who'll win 2012 Hero of the Year!"
