Rihanna's Shaggy New Bob Haircut Is All Grown-Up (PHOTOS)

Seems like someone is tired of hearing all about Jennifer Lawrence's pixie.

Rihanna debuted a new shaggy haircut on Instagram on Monday and girl looked all grown-up!

Rather than go short à la JLaw, Miley Cyrus and Pamela Anderson, the 25-year-old sported a messy bob - an update on the chic '20s-inspired 'do she wore in 2007.

RiRi sent a shoutout to hairstylist Ursula Stephen, who we presume was responsible for chopping off Chris Brown's ex's locks.

Bobs are becoming a huge trend in Hollywood and are arguably even more popular than the ever-present pixie. Jennifer Aniston is the most recent red carpet vixen to adopt the cut and actress Lily Collins recently sported the bob's cousin, the lob.

Rih got so excited over her new 'do that she celebrated by dressing up in a velvet catsuit and thigh-high boots to meet friends for dinner in New York.

What do you think of her new hair?

Werk it, Rihanna!
