Miley Cyrus hit the red carpet with her beau Liam Hemsworth Sunday night for the CNN Heroes: An All-Star Tribute event, and like her gown at the American Giving Awards, she was sporting serious cleavage!









Miley sported a sexy side braid, a light yellow Roberto Cavalli gown with Alaia heels and Neil Lane jewelry, but her best accessory was Liam. Her tall drink of water suited up for the good cause, and stayed on his gal’s arm for most of the red carpet photo ops.

Miley tweeted from the event: “What a glorious night to be apart of. Thank you for having me on your stage @CNN Such an honor.”

The pop star performed at CNN Heroes, singing her song “The Climb.”
