Her NBC show was just canceled, but Vanessa Hudgens already has a big new gig!

The actress and singer, 28, will co-host the 2017 Billboard Music Awards — which airs live from Las Vegas’ T-Mobile Arena on Sunday, May 21.

She’ll be joined by rapper and actor Ludacris — back for his fourth straight year hosting.

“I’M BACK FOR YEAR NUMBER 4 so I must be doing something right!” the 39-year-old star wrote on Instagram.

Hudgens also posted about the gig on Instagram — writing, “I’m so unbelievably excited to host the @BBMAs this year with @Ludacris!”

This year’s show is expected to bring yet another round of superstar performances and unexpected collaborations including showings from Bruno Mars, Camila Cabello, Drake, Ed Sheeran, Imagine Dragons, Lorde, Nicki Minaj and Miley Cyrus — the latter singing her new single “Malibu.”

The Chainsmokers are set to perform their new hit single “Young” — while Halsey will perform “Now Or Never” from her forthcoming album, and Sam Hunt will perform his No. 1 Billboard Hot Country Songs hit “Body Like a Back Road.”

Florida Georgia Line and John Legend will team up for a superstar duet, mixing their country and soulful pop styles in a cover of mashup of FGL’s “H.O.L.Y.” and Legend’s “Surefire.”

Céline Dion will also take the stage to celebrate the 20th anniversary of her smash hit “My Heart Will Go On.”

And “Believe” it or not, Cher is turning back time with her first live awards show performance in more than 15 years — performing her ’90s anthem, “Believe,” and accepting the show’s ICON award. (Previous winners include Jennifer Lopez, Prince, Stevie Wonder, Neil Diamond, and last year’s winner, Dion).

Drake and The Chainsmokers lead the nominees with 22 nods each, and Twenty One Pilots follow with 17 nominations, Rihanna with 14, The Weeknd with 13 and Beyoncé with eight.

The Billboard Music Awards airs live on May 21 (8 p.m. ET) on ABC.
