Having just kicked off another year of academic endeavors, Kylie Jenner gleefully strolled about Calabasas following the day's lessons on Friday afternoon (September 3).

Joined by a few gal pals, the youngest of the Kardashian/Jenner clan donned a black tank top and matching short shorts while excitedly getting the Labor Day holiday weekend underway.

As previously reported by GossipCenter, Miss Jenner spent the prior evening alongside her family for the opening night of the Taste of Beverly Hills festival. Joining sister Kourtney, Scott Disick, brother Robert and parents Bruce and Kris Jenner at the soiree, the E! reality family were all smiles as they were presented with a "Key to the City" of Beverly Hills via Mayor Jimmy Delshad.

Still situated in the UK, Katy Perry was spotted greeting her adoring fans in London, England on Friday night (September 3).

Following another busy day of promotions, the "California Gurls" singer kindly spent time outside the Claridge's Hotel to sign autographs and pose for pictures before continuing along with her nighttime agenda.

Having released her new album "Teenage Dream" earlier this week, Katy was able to grab the top spot on the sales chart with 192,000 copies sold while "California Gurls" saw 3.6 million downloads. Despite the fact that she had the best numbers, industry experts were surprised by the low totals, as one source said, "I'd like to meet one industry executive last week who thought her album would do under 200,000 units, because I don't think that person exists." The insider adds, "It was a wake-up call for some folks. Some think the sky is falling. Others said, 'Wait a minute, she's a singles artist.' And still others said EMI should have put out the album six weeks ago and it would have sold more."Photo Credit: Wenn.com

Easing into the grind of everyday dance practice, Audrina Patridge was spotted out at a local studio in Hollywood, California on Friday afternoon (September 3).

Clad in her fitness apparel, the former "Hills" hottie strolled outside with her "Dancing with the Stars" partner Tony Dovolani following their grueling preparatory routine.

Tweeting to her recently announced dance mate pre-meetup, Miss Patridge wishfully wrote, "@TonyDovolani we should go rehearse at the beach today!! Hahah" Understandably worn down following their midday session, Audrina headed straight into relaxation mode, as she later tweeted, "Finally reached my destination!!

Seeking out new ways to spend her free time aside from her previous partying ways, Lindsay Lohan headed out for a night at the movies in Hollywood, CA on Friday (September 3).

Joined by a few friends, the "Georgia Rule" babe got the help of a security staffer as she made her way into The Grove to catch her just-released movie, "Machete".

Meanwhile, LiLo popped up in headlines earlier today over reports of a hit and run incident claiming that she clipped a baby carriage in her Maserati before speeding away. Since the initial story broke, TMZ sources tell that the tale was embellished - as it reportedly took place on Wednesday with Lindsay making a legal turn while "ever-so-slightly tapped the stroller -- like 1 mile an hour." Rather than just driving off, the TMZ insider tells that Miss Lohan stopped to make sure everything was okay before proceeding on her way.Photo Credit: Wenn.com
