Taking the stage for a dazzling performance, Rihanna was a hit at the 2010 Echo Awards at the Palais am Funkturm in Berlin, Germany on Thursday.

The Barbadian beauty switched out of her lovely green dress into a curve-hugging bodysuit as she performed her latest single “Rude Boy” for the amped up crowd.

The appearance comes just as RiRi broke a Billboard record as he single “Rude Boy” cracked the top ten by landing at the No. 8 spot.

Making for her 14th Hot 100 hit, Rihanna now holds the most Hot 100 Top 10s by a female artist since the beginning of the last decade.

Back to work on her hit show, Eva Longoria was spotted on the set of “Desperate Housewives” in Los Angeles on Monday.

Clad in a sexy mini dress, the brunette beauty kicked things off with a scene in which her character busily tries to sell Girl Scout cookies.

A short while later, Miss Longoria mustered up her inner animal lover as she toted around an adorable pet pooch ahead of a little more filming.

In related news, you can catch Eva making a guest appearance on the series premiere of the new Jerry Seinfeld series, “The Marriage Ref,” which airs on NBC on Thursday at 10PM.

Fresh from her big win at the Vancouver Olympics, Lindsey Vonn was spotted back in the US on Monday.

Dressed cute and casual, the 25-year-old alpine skier looked to be enjoying herself as she took to the shops on Robertson Blvd in Los Angeles, CA.

The outing comes just hours before Vonn is set to appear with Jay Leno for the return of the “The Tonight Show.”

Meanwhile, a recent National Enquirer tabloid report came out claiming that the gold medalist is negotiating a deal with NBC to appear as herself in an upcoming episode of “Law & Order.”

With a walk down the aisle looming ahead, Hilary Duff was spotted keeping in tip-top shape with a gym visit in Los Angeles, California on Wednesday.

Wearing all-black workout gear, the “Cheaper By the Dozen” cutie also sported her new engagement bling as she walked to and from her Mercedes SUV before and after the personal trainer session.

As for the fancy diamond ring bestowed unto Hilary by fiance Mike Comrie, it’s said to be a million-dollar, 14-karat princess-cut sparkler.

Continuing to push forth with her ultra-successful career, Rihanna’s latest song headed to the world of music videos happens to be “Rude Boy”.

Recently talking to press about the project, the Barbadian beauty told MTV Korea, “It’s really colorful; it’s a pop art video.”

RiRi continues of the “Rude Boy” video, “We shot it all on green screen. Everything was done in post-production. It’s really colorful, really energetic. It was really inspired by my Caribbean roots. I love reggae music. [Rude Boy] is a Jamaican term, so our costumes are dancehall-queen-like. It’s a fun video. Probably the most fun video we’ve done so far.”

Switching subjects to talk about her plans for the future, the 22-year-old says, “Rated R – I love the sound of it, in terms of the bass. I really like the bottom, the grime of it. But if I were to combine that with more energetic, uptempo pop records, then I think that will be a happy marriage. And that’s where we’ll probably go next.”
