Not only did the English-bred actor, 20, wow Agron's Glee costar Jayma Mays with his good looks and personality, but he also bonded with her husband Adam Campbell.
"[Alex] came on set, and my husband was there that day, so we introduced the Brit to the Brit," Mays, 31, told PEOPLE at Entertainment Weekly's Women in Film Pre-Emmy's bash Friday night in West Hollywood. "Brits hang tight. That's how they are."
All UK bonding aside, Mays is overall impressed. "He seems lovely," she says. "He seems like a really nice guy. He's really cute and she's beautiful."
And Mays says Pettyfer could come back any time he wants. "I think our cast is pretty welcoming," she says. "And he's nice to look at, so I'm sure all the girls on set will love to have him around."
