Heidi-montag-spencer-pratt "The Hills" starlet Heidi Montag has been busy.

She appeared in a shockingly low-cut and well-taped dress and made smoochy lips with Spencer Pratt on the red carpet at gossip blogger Perez Hilton's 32st birthday party at the Viper Room Sunday night.

And she's exclusively released her new single "Look How I'm Doing" to On-Air with Ryan Seacrest this morning.

She also released the second single "Your Love Found Me" exclusively to Perez Hilton. It's called spreading the wealth. Or perhaps the pain.

But you can listen to them both by clicking here.

Warning: Keep fingers poised near ears at all times to prevent irreversible brain damage.

Consider yourself warned.
