Yes, but he should pretend to be a girl.

A bald male with stubbly facial hair peered over Joan's shoulder. "OMG! You were right, he's sooooo cute!" he said in obvious falsetto. "Hi, I'm Joan's roommate, Michelle."

"Oh, uh, hi?" Mokuba replied.

The man dropped into his normal voice. "Sorry. I'm actually Michael. I know you're doing the whole 'pretending' thing but obviously I'm not convincing you. I just wanted to see your face once. I can stay out of your way from now on."

"OK. Sure, yeah, that sounds good," Mokuba said.

Joan took Mokuba's arm and headed towards the stairs. "Bye Michelle, don't wait up for me," Joan called over her shoulder. They made their way down to the parking lot and Mokuba opened the passenger door to an electric blue Tesla Roadster. "Is this thing for real?" Joan asked as she got in.

Mokuba got behind the wheel. "Ever since I met you, I don't know what's real anymore."

"Fair enough."

Again, the conversation remained restricted to light topics. With all the scenery flashing by outside the windows, Joan had an endless supply of inspiration.

They approached a building with a giant neon guitar neck sticking out of the first floor awning. Shimmering curtains shielded the windows from curious outsiders. When they stopped, a valet opened the door for Joan and took the keys from Mokuba.

Mokuba handed his passport to the bouncer, who quickly found him on the guest list. He then scanned Joan's ID and they were ushered inside with minimal delay. Once inside, Joan handed her purse over to the coat check person and Mokuba pocketed the ticket they received in exchange.
