Benny Blanco’s Fear of Flying Threatening Relationship With Selena Gomez and Their Upcoming Nuptials

Groom-to-be Benny Blanco’s fear of flying may ground his wedding plans with songbird Selena Gomez, concerned sources say.

The music producer — born Benjamin Joseph Levin — and the pop princess turned actress began dating two years ago and are planning a ceremony in the fall.

But sources say Selena’s frustration with her petrified Prince Charming has triggered doubts about their future together.

“Selena is not sure how their relationship can survive if Benny’s never willing to fly,” a source says. “She dreams of a life where they can hop on a plane and spend time together whenever they’re working apart — which is a lot.”

“But because of Benny’s flying phobia, she now realizes she’ll have to go alone or take time off from her super busy schedule if she wants Benny to be with her.”

The insider adds that since the “Calm Down” crooner, 33, and her 37-year-old honey hooked up, she’s had to do all the traveling to see him — and taken trips with friends and family to satisfy her wanderlust.

“She recently took her family to Turks and Caicos, sans Benny,” the insider says. “Last year, when Selena had to make a quick turnaround trip to Paris for work, she practically begged Benny to go with her — but he refused.”

Now an exasperated Selena is pushing him to see a hypnotist to deal with his phobia, according to pals.

“Unless Benny can get past this, Selena genuinely fears their relationship is destined to crash and burn,” says the source.
