When you get Simon Cowell to join “America’s Got Talent” as a judge, you get much more than snarky comments — the music mogul also comes with an impressive rolodex of stars.

Two of Cowell’s biggest discoveries are One Direction and Fifth Harmony, both of which were formed on his “X-Factor” franchise. The U.K. global sensation was formed on the British “X-Factor,” and the chart-topping girl band was put together on the American version of “The X-Factor.” Both groups signed with Cowell’s label, Syco Records.

Cowell, who joined “AGT” as a judge this season, says Fifth Harmony will come onto the NBC series to perform this summer. One Direction, however is in the midst of a hiatus, and will not.

“We’ll have Fifth Harmony definitely this year because they’ve got an album coming out,” Cowell told Variety in a recent interview, referring to their second studio album “7/27,” which was released in late May. “It will be fantastic to have them on the show.”

Cowell continued, “One Direction I don’t think we’ll see as a group for a while now, if I’m being honest with you. But the girls, definitely.”

Cowell’s comments on One Direction refer to the group’s current hiatus, which began earlier this year and is expected to last about 18 months — but has been rumored to be a breakup. In March 2015, the band dwindled from five members to four with the departure of Zayn Malik, who left to focus on his solo career. One Direction’s fifth studio album, “Made in the A.M.,” released in late 2015, was the first without Malik. The group consists of Niall Horan, Liam Payne, Harry Styles and Louis Tomlinson, and the foursome has assured fans that they are not splitting up, despite conflicting buzz.

As for Fifth Harmony, the five-member pop group — Ally Brooke, Normani Kordei, Dinah Jane, Camila Cabello and Lauren Jauregui — is in the midst of promoting their new album, fresh off their platinum single “Work From Home.”

“America’s Got Talent” airs Tuesdays at 8 p.m. on NBC.
