Hollywood star Paul Mescal was seen at Glastonbury Festival, appearing to inhale a substance during a lively night out.

The 28-year-old Irish actor, known for his role in "Normal People," was spotted among the crowd at The Other Stage on the third day of the festival. He partied late into the night, enjoying performances by various bands.

Mescal, dressed in a cap and a rolled-up sleeved shirt, was seen dancing with friends during a set by US band The National. An observer noted that he seemed to use a key to scoop a substance from a bag, which he then sniffed twice. The observer remarked that Paul appeared unconcerned about being noticed, laughing and dancing with his companions.

Earlier in the evening, Mescal was joined by his "Normal People" co-star Daisy Edgar-Jones. However, she left about 20 minutes into The National’s performance, while Paul continued to enjoy the festivities with his friends.

When reached for a comment, Mescal’s representative declined to respond.
