Rupert Grint Casts a Spell on a Mystery Gal

Just because he’s busy filming Harry Potter and the Deathly Hallows by day doesn’t mean he can’t have his fun at night.

The 20-year-old actor, who plays Ron Weasley in the wizard-centric film series, was spotted prowling around London borough of Camden on Saturday night with a mystery woman by his side.

The pair emerged from a bar well after 2 a.m. and enlisted the services of a mini cab to usher them home safely.

Smart move. Not even Dumbledore would be able to save Grint from the negative publicity of a DUI arrest.
