The singer previously shared a similar message while performing at the TikTok Tailgate earlier this year.
Miley Cyrus is voicing her support of Britney Spears.
The singer performed at the grand opening of Resorts World Las Vegas on Sunday, where she belted out a rendition of her 2009 hit song "Party in the U.S.A" and shared a message of support to the Princess of Pop amid her conservatorship battle.
Cyrus changed a small part of the track's lyrics, singing, "The taxi man turned on the radio, he turned to me and said, 'Free Britney, Free Britney!" as many fans chanted along with her.
The original lyrics state that a JAY-Z song was playing on the radio. However, Cyrus later explained to the crowd that "we love JAY-Z, but we got to free this b***h! It’s stressing me the f**k out!"
This isn't the first time that Cyrus expresses her support to the 39-year-old songstress. Earlier this year, she shared a similar message during her TikTok Tailgate performance ahead of the Super Bowl in February.
As she once again sang "Party in the U.S.A", the Hannah Montana alum sent some love to Spears by telling the audience, "We love Britney!"
Cyrus is among the many celebrities who have expressed their support to Spears following her powerful comments during a court hearing last month.
