Heidi Montag and her husband Spencer Pratt were tapped to host a pre-Valentine's Day party at Pure Nightclub in Vegas on Saturday night.  Montag posed in a red dress that resembled an elongated Valentine heart, showcasing her new and improved chest.

She chatted about the ten procedures that she had done in a marathon session in November.  Heidi said,  "My favorite part?  I think one of them is my chin.  I think that's what I was so excited about.  And I love my boobs but I still want to improve.  I didn't get them as big as I originally wanted."
