Hollywood Headlines: A week in review

Add “Cupid” to his resume. Timberlake’s love arrows shot true when he called a couple onstage during a Kentucky performance, handed his microphone to “Mr. Right” and let the groom-to-be steal the show. And steal the show he did — we’re not sure we’ve ever heard fan screams so loud.  (John Shearer / Invision / Associated Press)

The 19-year-old pop star continues to wield his fame without regard to consequences (e.g., defiling a custodial bucket with his urine), with his latest stunt possibly causing Bieber fan emotional haywire worldwide: “After the new album, I’m actually, I’m retiring man, I’m retiring,” he told L.A.’s Power 106 radio station. According to his crew, the announcement was just a joke.  (Powers Imagery / Invision / Associated Press)

Unlike Bieber, Gomez is taking a real hiatus from music. The singer canceled her Australia tour dates, and reports say her Asia stop may also be nixed. “It has become clear to me and those close to me that after many years of putting my work first, I need to spend some time on myself in order to be the best person I can be,” Gomez said in a statement. Sources say she’s fine, just a tad homesick.  (Taylor Hill / Getty Images for Clear Channel)

Rumors that Dodgers player Matt Kemp is Khloe’s new man surfaced less than a week after the youngest Kardashian sister’s divorce filing, leaving the celeb running to Twitter with a plea: “This, in and of itself, is heart breaking and torture to my soul,” she wrote. “Please, I don’t need the extra rumors and BS right now.” The Kardashian sister filed for divorce from NBA basketball player Lamar Odom due to “irreconcilable differences,” after more than four years of marriage.  (Chris Pizzello / Associated Press)

Singer Demi Lovato seems to be missing the stage. Retiring from “The X Factor” after two seasons as judge on the music competition show, Lovato says she’s ready to focus on touring and recording a new album.  (Richard Shotwell / Invision / Associated Press)

Is that the glow of a healthy mom-to-be, or the media spotlight? It might be both. The “Her” actress has been seen with a noticeable belly swell at the Golden Globes nominations, the premiere of her newest film and other red carpet events since she first announced her pregnancy in October.  (Robyn Beck / AFP / Getty Images)
