Rupert Grint headed to Las Vegas this weekend, where he celebrated his birthday nearly a month after the actual date at the Chateau Nightclub & Gardens at the Paris Las Vegas and Sugar Factory American Brasserie - where he will be doing a mass fan meet and greet later today - on Saturday evening. Photos of the Harry Potter actor enjoying a lollipop at the Sugar Factory, posing on the red carpet outside the Chateau, and dining away with a Hogwarts-inspired cake and sweets inside the venue can be found in our galleries. We will have more on Rupert's fan meet and greet later today.
