Kim Kardashian wore an Agent Provocateur bikini during a recent trip to Miami. She played on the sand with her publicist pal Jonathan Cheban, and even stretched out her legs on an old pier. Kim was in Florida for some fun with her friends, but has since returned home to LA. She spent yesterday with her nephew, Mason, tweeting, "Fun day at church with Mason today, then a BBQ and swimming with friends and family. Couldn't have been a more perfect Sunday!"

She's had to break from time with her young relatives to do a bit of work lately. Kim's shared behind-the-scenes looks at a few recent photo shoots. Kim wore a two-piece in a pool for one aquatic-themed spread, and also posed with her sister Khloé. The whole Kardashian gang has also been taking meetings for their new makeup line, Khroma. Her boyfriend, Kanye West, is also focusing on work. Kanye's new music was the center of attention Friday, when he debuted previously unheard tunes at the Dream Downtown during an evening out with Leonardo DiCaprio.

Miranda Kerr and Orlando Bloom boarded a yacht as they left Hamilton Island in Australia yesterday. The family of three was on vacation in the exotic location and stayed at the luxurious Qualia Resort. Miranda shared pictures on Twitter and wrote of the spot, "Most beautiful place on Earth." It may have been a belated celebratory getaway, since Miranda and Orlando's second wedding anniversary was in late July. The couple was back together after their busy schedules kept them apart for part of last month. Miranda took care of business and stepped out with Flynn in NYC, while Orlando traveled to London to attend an event. Miranda and Orlando were the subjects of divorce rumors recently, but Miranda's rep quickly denied that there is any trouble between the duo.

Kate Middleton ventured to Weymouth, England, today to watch Olympic sailing. She was on a boat, armed with binoculars, to see the women's Laser Radial competition. China's Xu Lijia won, while Kate's own Team GB's Alison Young came in fourth and the USA's Paige Railey was number six.

Kate was joined by her husband's aunt, Princess Anne, as well as Anne's husband, Sir Timothy Laurence, who has some familiarity with the water as a retired British naval officer. Kate's likewise demonstrated her own interest in aquatic sports. She practiced helming a dragon boat for a 2007 competition across the English Channel, though she had to drop out due to security concerns. During a stop on Prince Edward Island during her Canadian tour in 2011, Kate raced William in a dragon boat. William was the victor in that matchup.

Reese Witherspoon wore spandex to hit the streets of LA today for a workout with a girlfriend. The exercise session came after a low-key weekend for Reese that included plenty of family time. Yesterday, Reese picked up drinks at a Coffee Bean & Tea Leaf while her husband, Jim Toth, and son Deacon waited in their car. Reese and Jim are growing their family in the coming months, but that hasn't slowed her down work-wise. Reese has logged time on the set of Devil's Knot this Summer and is producing a big-screen project based on the hit thriller book Gone Girl.
