That pretty brunette you saw before is Lady Gaga's little sister, Natali Germanotta!

She's six years Gaga's junior, and is currently a fashion student. Even though she tends to fly under the radar, she supports her sis Stefani in every one of her ventures, escorting her to red carpet events, and she also appeared in Gaga's 'Telephone' music video -- scroll to 2:16 to see her!
