With all the attention on his love life, Justin Bieber still faced the music — and the paparazzi — when he ventured on a shopping trip in West Hollywood on Friday.

The recently-single (or not) 18-year-old superstar was spotted rocking a denim vest, camouflaged pants and a backwards baseball cap while taking a break from his Believe tour.

On the East Coast, Sarah Jessica Parker looked stylish from head-to-toe, as she headed to a lunch date in Manhattan. The Sex and the City star took advantage of the beautiful fall weather in a pair of cropped pants, army green pumps and long beige coat.

Speaking of style, new mom Kristin Cavallari was caught leaving a hair salon in Beverly Hills on Friday. The 25-year-old must have been pleased with the results — as she grinned ear-to-ear while sporting a pair of stylish bellbottom jeans and an oversized grey purse.

In other sightings, Rihanna continued her 777 Tour — seven cities in seven days — by jetting from Toronto, Canada to Stockholm, Sweden for show number three. The “Diamonds” singer launched the special tour on Wednesday, all in support of her upcoming album Unapologetic.

On the red carpet, Jennifer Aniston flashed her gorgeous engagement ring as she attended the 26th American Cinematheque Award Gala with fiancé Justin Theroux. This year’s award went to Ben Stiller, who attended the event with wife Christine Taylor.
