Television personality Jeannie Mai and retired NFL tight end Rob Gronkowski have been added as co-hosts on “Dick Clark’s New Year’s Rockin’ Eve with Ryan Seacrest.”

Mai is presiding over festivities in Los Angeles and Gronkowski will co-host from Las Vegas from the Fountains at the Bellagio Resort. The West Coast party hosted by Mai will include performers such as Alanis Morissette, with special guest Reneé Rapp, Dasha and DJ Cassidy’s Pass The Mic Live!, a performance that includes stars like Ja Rule, Kesha, Natasha Bedingfield, T-Pain and more.

Ryan Seacrest is slated to host the broadcast for the 20th time alongside co-host Rita Ora in NYC’s Times Square, featuring previously-announced musical performers The Jonas Brothers, Carrie Underwood, Megan Moroney and Sophie Ellis-Bextor, taking the stage before the ball drops in Times Square at midnight.

Set to take the stage in Las Vegas are Blake Shelton, Cody Johnson, Thomas Rhett and Lenny Kravitz; and Jungle will perform from London, playing songs including their hit song “Back On 74.” The network said in a press release: “In his 20th year as host of America’s most-watched New Year’s Eve special, Ryan Seacrest will lead the countdown to midnight alongside global superstar Rita Ora live from Times Square, Dayanara Torres returns as co-host in Puerto Rico.”
