Shia LaBeouf: Silverado Gas Guzzler

Shia LaBeouf is still looking to bulk up!

The 23-year-old Transformers actor was spotted gulping down another bottle of chocolate-flavored Muscle Milk. Exactly three weeks ago, he was spotted with another bottle of the same protein-enhanced formula.

Shia was also seen filling up his Chevrolet Silverado pick-up truck at a local gas station. When he spotted a photographer in the distance, he seemed very upset.

FYI: Shia is wearing his favorite Menard t-shirt and PF Flyers Number 5 Sneakers.
