Frankie Grande likes to stay busy — even on Sundays.

“From the moment I wake up, it’s go, go, go,” said Mr. Grande, a 41-year-old actor, singer and reality TV personality. This month, he returned to playing Victor Garber in “Titanique,” an Off Broadway parody musical of the movie “Titanic.” He first played the character in a fully staged production in 2022, and is now back for a limited run through Feb. 18.

Mr. Grande, who is the half brother of the pop superstar Ariana Grande, was born in New York, grew up in Englewood, N.J., and Boca Raton, Fla., and graduated from Muhlenberg College in Pennsylvania. Now he splits his time between a two-bedroom penthouse apartment in Hell’s Kitchen and a home in Beverly Hills, Calif. He lives with his husband of almost two years, the actor and model Hale Grande, 31, and their red toy poodle puppy, Appa.

While Mr. Grande was a relative unknown when he moved back to New York City in 2005 — he said he often wandered through Times Square wearing a pair of earbuds, soaking in the scene — he’s now a YouTube, Instagram and TikTok personality with more than 3.5 million followers across all three accounts.

“I definitely can’t wander now without being recognized every four feet,” he said. “But I love talking with fans.”

HERE COMES THE SUN I don’t usually get up before 10 a.m. — my husband is in Los Angeles for work, and we’d been up all night playing the new Avatar: Frontiers of Pandora game — but I surprise myself and wake up at 8:45 a.m. I have a Philips alarm clock that mimics a natural 30-minute sunrise, and at the end it has birds chirping. It wakes me up like I’m on a farm with animal noises. It’s a really peaceful way to start the day.
