Mariah Carey has new representation…

A day after the 45-year-old half Venezuelan singer and her longtime publicist Cindi Berger parted ways, Carey announced her new PR and management team.

Chris Chambers of the Chambers Group, who’s worked with Lil Wayne, Drake and many other artists over his long career, will her as her PR agent. Her fifth set of managers since 2013: TV producers Brian Sher and Stella Bulochnikov.

Carey’s new managers have worked together on several projects, most recently E!’s Christian Milian Turned Up and VH1’s T.I.’s Family Hustle and Tiny & Shekinah’s Weave Trip. Sher, who has worked as T.I.’s agent since 2004 and his co-manager since 2009, has been credited with helping to rebrand the rapper’s image via the television shows.

Sher began his career as a production assistant before beginning his career in ICM’s mailroom. He rose to the role of agent in 2000 and left in 2008 to form Category 5 Entertainment, where he begin working with T.I., Michael Vick (executive producing The Michael Vick Project for BET) and partnered with Kelsey Grammer in Grammnet NH.

Bulochnikov is a producer and writer who’s worked with Sher on Boss, T.I. & Tiny and Larry the Cable Guy’s Star-Studded Christmas Extravaganza.  She has a long history as a producer with Viacom shows dating back to 2001, including VH1 Divas, I Love the ‘80s and ‘90s, and several Paris Hilton Specials.

The moves come ahead of several big projects for the singer, who has stumbled in recent months with the poor sales of Me. I Am Mariah … The Elusive Chanteuse, the lowest-selling non-holiday studio album of her career and several wobbly live performances. On May 6, she begins a Las Vegas residency at The Colosseum at Caesar’s Palace, the same venue where Celine Dion will return on Aug. 27 after a year-long hiatus. Also expected later this year is a newly repackaged greatest-hits set called #1’s, the first release in her new deal with Epic Records, to accompany her Vegas show. She also has a Christmas movie on the horizon, according to Deadline.

Among other chart feats, Carey holds the record for total time spent at No. 1 on the Billboard Hot 100, 79 weeks total, and also holds the record for longest-running Hot 100 No. 1 single (for 1995’s “One Sweet Day” with Boyz II Men, 16 weeks at No. 1), although she hasn’t had a Top 10 single since 2009’s “Obsessed.”

Carey had three management teams in 2013 alone, beginning with a Randy Jackson/Irving Azoff partnership, then Bruce Eskowitz of Red Light Management and then Jermaine Dupri, who produced some of her biggest hits including “We Belong Together.” Dupri gradually gave way to Kevin Liles, who semi-officially took the reins in August of 2014 but recently dropped out.

The news was first reported by Page Six and confirmed to Billboard by Chambers Group.
