Rihanna arrives for fancy lunch with messy bed hair.

Rihanna proved that not even a bad hair day can ruin her fabulous look while out in Beverly Hills this week.

The 26-year-old singer rocked a messy 'do and fresh-faced make up for lunch at Il Pastaio Ristorante in the posh neighbourhood on Tuesday.

While her locks were unkempt, she looked otherwise perfectly groomed.
