New York City was blanketed by snow last night, but this morning Lauren Conrad kept herself warm and cozy in a familiar yellow jacket for her GMA appearance.

Sweet Little Lies was released yesterday, but Lauren and friends celebrated last weekend with a Vegas bash, which was perfectly timed since she also celebrated her 24th birthday on Monday.
