Hayden's Indestructable $hopping $pree

With tonight's season finale, "Heroes" star Hayden Panettiere is hanging up her cheerleading uniform -- at least for the summer!

But it looks like the 17-year-old won't be lacking any outfits. TMZ has learned that on a recent retail blitz at trendy Beverly Hills boutique Harmony Lane, Hayden dropped over $2000 on dresses, tops and jewelry. Save the aggravation. Save the receipt!

Sources tell TMZ the underage beauty spent over an hour picking out items like a sexy $289 Voom Butterfly dress, a plush $289 Deborah Lindquist cashmere skull cardigan and $84 Vita bracelets/necklaces. Even superheroes like to accessorize! We're told Hayden kept talking about how excited she was to be a part of the hit show and how the whole cast goofs around a lot on set. Saving the world from total destruction can be such a pissah!

While on this trip she came alone, we're told Hayden mentioned how she normally loves to shop with her mom. When you're as gorgeous as Hayden, parental guidance is always suggested!
