Madonna traded in her leotards, thigh high boots and tiaras for a comfy workout ensemble when she attended a Pilates class in Los Angeles on Wednesday.

The Material Girl donned an all-black outfit, consisting of Victoria's Secret sweatpants, black shirt and black vest.

Last month, the workout queen opened the eighth location of her Hard Candy Fitness spot in Toronto. The "Like a Virgin" singer and her personal trainer Nicole Winhoffer led 50 members of the gym in an Addicted To Sweat class, which Winhoffer designed to give a cardio and toning workout.

Reportedly, the 55-year-old does this intensive class six days a week. Winhoffer explained the appeal of the class which is on all the Hard Candy Gyms’ schedule:, "[The classes] are challenging and you will get a full body workout. Dance is key and a big part of our workout."

We'd tell Madonna to keep it up -- but we know she doesn't need our words of encouragement!

Later that day, the aging singer showed off her sexy side when she grabbed her tiara and gave her shower door a good lickin' and then posted a pic to Instagram! All in a day's work when you are the queen of pop!

He's still wearing his wedding ring, though!

Olivier Martinez grabbed dinner at RivaBella in West Hollywood last night without wife Halle Berry, and we really hope the rumors that they're on the verge of divorce aren't true!

Reports are circulating that the couple are on the outs due to their hectic schedules, and that they are living separate lives and a split is imminent. The Oscar winner and the French actor haven't been seen together publicly since December, and the actress stepped out to a post-Oscars party on March 2 without her wedding bauble.

They pair welcomed son Maceo last October, and if we had to guess we would assume the stress of new parenthood isn't helping their relationship either.

We hope they work things out!

So this is how she stays so skinny!

Victoria Beckham paid a visit to Conde Nast college in London yesterday, and the designer got to try out a new treadmill that doubles as a work desk. Talk about making the most of your time!

Only VB would climb on an exercise machine in sky high heels!

"Every office should have one of these. Work out and work at the same time!! Genius!!" she captioned the Twitter snapshot.

The former Spice Girl was invited to the school to speak to students about a career in the fashion industry.

She has really made a name for herself!

Gotta get back to little miss Nori!

On Thursday morning Kim, Khloe and Kourtney Kardashian jetted out of Miami, and while they had a blast opening the Dash boutique the previous day, it looks like everyone was ready to come home to Los Angeles.

The group was staying in the old Versace mansion in South Beach, and before heading to the event, Kim K snatched little sister Kylie's strappy black bikini and ripped a few selfies. Click HERE in case you missed those...

Lindsay Lohan is walking down the aisle! Well, on the small screen anyway...

We already knew the 27-year-old actress was guest-starring on 2 Broke Girls, and both Lilo and her co-star Kat Dennings posted pictures online of themselves in wedding dresses yesterday. While Lindsay is notoriously difficult to work with, it looks like the ladies had a blast!

Kat wrote, "Sh*t gets real in upcoming episodes of 2 Broke Girls," while Lilo added, "sharing with you guys a preview wedding moment on set #2brokegirls xo L."

Lilo will play neurotic bride-to-be Claire Guinness, who asks Max Black (Dennings) and Caroline Channing (Beth Behrs) to make her wedding cake. The episode airs on April 14.

Loves her!

On Wednesday afternoon Britney Spears and boyfriend David Lucado hit the gym in Los Angeles, and the pop starlet was all smiles after her workout. Despite the fact that it's 2014, it looks like Brit Brit is still hanging on to her fav workout outfits from a decade ago. Remember her short-lived reality series called Chaotic? There's a scene of Britney on a treadmill and she's totally rocking a tee and a pair of sweatpants just like this...

In other news, Britney reportedly wants to marry David at Elvis Presley's Graceland estate, and while there's no confirmation that the duo are even engaged, Brit's clearly already put some thought into walking down the aisle...for the third time. A source tells Radar, "Not only would the Graceland location, now a tourist attraction, be a visually stunning place for Brit and Dave to tie the knot, but it would be a convenient trip for most of their extended families, who are based in the south ... If Lisa Marie, who controls the Graceland estate, gives her okay, Britney will start her wedding planning with a vengeance."

And not just any bikini -- it belongs to her 16-year-old sister!

Kim posted the above shots and wrote, "Quick swim before the Dash party ... Yep, stole Kylie's bikini...she's not getting it back." We think Kylie will beg to differ, especially since she posted her own selfie in the same bikini earlier in the day!

It appears as though the sexy snapshot was taken in the bathroom of the Versace Mansion, and while Kim barely squeezed her boobies into the top, we have to say, she looks pretty incredible! We're surprised Kanye's not hopping on a jet and heading over there right now...

Talk about his day going in the wrong direction!

Harry Styles stopped by Craig's in West Hollywood on Wednesday, and what was supposed to be a nice leisurely lunch ended up being a bit chaotic! First The One Direction singer was mobbed by photographers and fangirls, and then his bike broke down when he was driving to the Westside ... yikes!

Thankfully Harry or someone he knows has AAA, because the boy bander and a cheerful pal rode in the cab of the tow truck to a local repair shop. Maybe he'll think twice about tooting around town on a vintage bike next time? Then again, it is pretty hot...
