The two are not strangers, in fact, they’ve known each other for some time. Based on his LinkedIn, he’s known her since November 2018, which was when he signed on to be her monitor engineer.

He’s also worked with other artists such as Camila Cabello, Bruno Mars, Justin Timberlake, Taylor Swift and Jay-Z.

He also worked with the sound department team for The Tonight Show Starring Jimmy Fallon and Glee: The 3D Concert Flick. Horton also previously owned his own company, the Audio Engineering Consulting Group, for two decades.

His work got the attention of Lenny Kravitz, who is a huge fan. In 2012, the rockstar called Horton personally to have him on his tour.

“He wanted to see what I would do differently,” Horton said in an interview.

Before Gaga, he wed singer-actress Autumn Guzzardi.

The new relationship comes after the Oscar winner called off her engagement to Christian Carino. They were together for two years.

Fans have also speculated that Gaga and Bradley Cooper were together after filming A Star Is Born together. However, Gaga admitted that it was just a stunt.

“Yes people saw love and guess what? That’s what we wanted you to see!” the singer said. “The movie A Star Is Born, it’s a love story.”
