No one “Believes” in Bieber

Maybe the real reason Justin Bieber wants to retire is because nobody “Believes” anymore. According to the Hollywood Reporter, the 19-year-old’s documentary “Justin Bieber’s Believe” bombed at the Christmas box office, bringing in $3.1 million in its first three days. It is expected to take in $4.5 million in all, far below the $29.5 million debut made by its predecessor, “Never Say Never.” “Believe” is supposed to be a behind-the-scenes look at the singer’s rise to international fame. Now, it could signal the beginning of the end. Last week, Bieber abruptly stated that he was retiring from the music industry. “My beloved beliebers I’m officially retiring,” the singer tweeted. 2011’s “Never Say Never” grossed $73 million domestically, while “Believe” is on pace to make only $10 million.

The 90-minute, 24-song concert is the first of 100 that Spears will be performing during her Vegas stint. Spears performed many hit singles from her discography — “Toxic,” “Womanizer,” “3,” “Oops!…I Did It Again,” “Baby” — and received some unexpected help from the audience.Miley Cyrus became a part of the show during an interlude, when Spears’s dancers walked through the audience. The 21-year-old played along, stroking the face of one of the dancers. While performing “I’m a Slave 4 U,” Spears wanted a “hottie” to join her on stage. Who else but television host Mario Lopez got up there, allowing himself to be put in a harness and “spanked” by Spears. Katy Perry, Selena Gomez and Adam Lambert were also in attendance.
