ABC and Dick Clark Productions have announced more of the lineup for "Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2017." Via press release on Tuesday, the companies added Alessia Cara, G-Eazy, Martin Garrix, John Legend, Mike Posner, Bebe Rexha, Hailee Steinfeld, and Flo Rida featuring Macy Kate to the "Billboard Hollywood Party," which is the second stage for "Rockin' Eve" that's based on the West Coast.

They join previously revealed performers Fifth Harmony featuring Kid Ink and Ty Dolla $ign, Niall Horan, Lukas Graham, Shawn Mendes, Emeli Sande and Fergie, the latter of whom will also serve as host for the "Hollywood Party" portion of the program.

Cara is one of the pop sensations of 2016. She recently performed "How Far I'll Go", the lead single from Disney's latest animated film "Moana." She was a 2016 American Music Award nominee for Best New Artist and her most recent single, "Scars To Your Beautiful", has already reached more than 16 million views on YouTube. Cara has toured with Coldplay and also headlined her own "Know-It-All Tour" this year.

G-Eazy represents the hip-hop contingent fresh off the release of sophomore album When It's Dark Out, which rose to number one on the Billboard R&B/Hip-Hop Albums Chart and was subsequently certified Platinum by the Recording Industry Association of America. The record's hit single "Me, Myself and I" features Rexha, but ABC and DCP didn't reveal Tuesday if the two will be performing together at "Rockin' Eve" or not.

Electronic artist and producer Martin Garrix has been named to Forbes' "30 Under 30" list three times while winning four MTV European Music Awards. Like G-Eazy, Garrix worked with Rexha on his hit single "In The Name of Love", which boasts 239 million YouTube views - so will they collaborate again on the "Hollywood Party" stage?

Flo Rida will be teaming up with teen singer Macy Kate, who is signed to his record label, while ABC and DCP didn't give details on what Posner - known for his smash hit "I Took A Pill In Ibiza" - Legend or Steinfeld will be doing.

They're just some of the many artists that'll be on the bill for New Year's, and that's only on the left side of the country. Per Tuesday's press release Mariah Carey, DNCE, Thomas Rhett and the cast of Broadway's "On Your Feet" featuring Gloria Estefan will perform during the New York part of "Dick Clark's Rockin' Eve." Jenny McCarthy will report from Times Square.

"Dick Clark's New Year's Rockin' Eve with Ryan Seacrest 2017" airs Dec. 31 at 8 p.m. ET/PT on ABC. For more on any of the newly announced artists, click their names at the top of this article to visit their artist pages at AXS.
