Frankie Grande Reveals How Sister Ariana Grande Is Helping Him on Broadway

Frankie Grande is a Broadway veteran, but he's still leaning on his pop star sister, Ariana Grande, for support as he opens Titanique.

"Ariana has been my vocal doctor," Frankie, 43, who is originating the role of Victor Garber in the campy musical, told Us Weekly exclusively on opening night at New York City's St. James Theatre on Sunday, April 12, which marked the famed ocean liner's first day at sea 114 years ago. "She texts me all the time. She's sent the same pastilles that she uses and her same vocal routine, so yes, she's been helping me through this very difficult process of opening a Broadway show."

He continued: "It's been really taxing on my body and my voice, so she's been helping me with my voice, and it's been awesome. Her and [vocal coach] Liz Caplan."

Both Grande siblings got their start on Broadway, with Frankie joining the cast of Mamma Mia! in 2007 and Ariana starring in 13 in 2008 before getting her big break on Nickelodeon's Victorious.

While some members of the cast share names with their movie counterparts (see: Jack and Rose), Frankie's character is Garber himself, who played shipbuilder Thomas Andrews in the original film about the 1912 maritime disaster.

While Dion hasn't yet been to see the show, Garber did stop by during its run Off-Broadway.

"Victor came and he spoke to all of us after and he said, ‘I've gotten to a point in my life where I've started to wonder how I will be immortalized and what my legacy will be, and I never thought it would be this,'" Frankie told Us of the actor's visit. "He loved it so much."

Costarring alongside Mindelle and Grande are Rousouli as Jack Dawson, Jim Parsons as Ruth DeWitt Bukater, Melissa Barrera as Rose DeWitt Bukater, Deborah Cox as the "Unsinkable" Molly Brown, John Riddle as Cal Hockley and Layton Williams as The Iceberg.

Titanique is now playing at the St. James Theatre. Tickets are available online.
