Is That Really You Rihanna?

She normally looks like she is ready to dance at a nightclub with short skirts, high heels and plunging necklines.

But on Sunday Rihanna pulled off a much more demure style as she stopped by the LA premiere for Home, for which she voices the character of Gratuity 'Tip' Tucci.

The 27-year-old Diamonds singer, who is thought to be romancing Leonardo DiCaprio, wore a long light pink satin gown that looked like something Audrey Hepburn might have worn in the 1960s.
