Dressing up her curves in short shorts, high-heeled boots and an adorable grey jacket, Hilary Duff and hubby Mike Comrie toted their darling son Luca on a shopping trip for fine art in Beverly Hills, on Saturday afternoon.

The former Disney star must be a Marilyn Monroe fan, because we spotted Mike carrying out a huge Andy Warhol-inspired piece that featured the iconic Hollywood star, from the Hamilton-Selway Art Gallery.

Later the family of three checked out a few houses in Beverly Hills; they must be in the market for a bigger love nest!

Kristen Stewart may have called her affair with Rupert Sanders a "momentary indiscretion," but now the director's brother-in-law has come forward to claim what has already been suspected: the pair have been hooking up for months.

Leopold Ross, the brother of Sanders' actress wife, Liberty Ross, told the Brit newspaper, The People:

“It was from the last half of filming and all through post-production, clear into last week.”

Since Snow White and the Huntsman shot from September 19 to December 10, 2011, Leopold says the affair actually started last fall, which explains why Stewart was on set most days of filming, even when she wasn't in the actual scenes.

Ross, who played the Twilight star's mother in the flick, left England with Rupert so that he could pursue his career as a director in Hollywood, but her brother says:

“She made some sacrifices for something she thought was worth it, now she knows, right? Five minutes from her home.... Doubt it was worth it but it’s life. It might actually make things better in the long run. She wasn’t that happy for a while, but our family is close, she’ll be all right."

We recently spotted moving trucks outside of the lavish Los Feliz home Robert Pattinson and Stewart share, which they have both since moved out of, after the cheating scandal broke this week.

Aside from the looming press tour for the finial Twilight flick, Stewart and Pattinson are also slated to appear together at MTV's Music Video Awards September 9.

Will they work it out by then?

It appears Kellan Lutz is using his Saint Tropez vacation to get into character for the title role in the upcoming Tarzan flick, because the actor was giving his best impression of the classic character while chilling on a yacht with Aussie girlfriend Sharni Vinson, and famous designer Roberto Cavalli, on Saturday afternoon.

The Twilight star made the most of his time out on the yacht, taking a jet ski for a spin and making Olympic-worthy dives off the side of the massive ship, before showering the sea water off his sexy 'bod.

Could he be any hotter?

Careful, Brooke!

Charlie Sheen's stunning ex-wife enjoyed a posh dinner at Sushi Ike in Hollywood with her new boyfriend, country star Jaron Lowenstein, but she appeared to be having a bit of trouble with her sexy high-heeled boots!

Miss Mueller looked hippie-chic in tan leather pants, a loose-fitting blouse, piles of turquoise jewelry and a pretty crystal headband, so it's a shame those shoes caused a minor slip-up.

The busy mom-of-two has been embracing the rugged look every since hooking up with her new country singing beau, and it was actually Sheen who introduced the pair while they were in the process of reconciling.

Later, the pair shared a romantic kiss -- they make such a beautiful couple!

See what you're missing, John Mayer?

Flaunting her fabulous figure in a green and gold bikini, Katy Perry appeared to be enjoying her relaxing vacation in Miami, on Friday as she lounged poolside with friends for the second day in a row.

The "California Gurls" singer's divorce from Russell Brand was finalized last week, and it's been rumored that the sexy songstress has already set her sights on ladies' man John Mayer. The two were reportedly seen getting cozy at private club Soho House in West Hollywood, and they were holding hands and cuddling, according to Us Weekly.

It has also been rumored that Katy invited John over to her LA pad for pizza. How romantic!

Ryan Phillippe is such a doting dad!

The Cruel Intentions star spent the day with daughter Ava and son Deacon on Friday afternoon, and he even treated the stunning 12-year-old to a trip to the nail salon in Hollywood.

While ex-wife Reese Witherspoon prepares to welcome baby No. 3, Philippe has been spending even more bonding time with his darling kids -- they're growing up so fast!

The Oscar winner recently told Britain’s TV show Daybreak about her daughter's upcoming 13th birthday, in September: "I don’t know anything about teenagers, so I’m on a big learning curve here. This is the time where I start asking all my friends who have kids who are older, ‘What do you do about a cell phone? What are your rules about the computer? Is she allowed to go out with friends or is she not?’ So I learn a lot from other mothers.”

Ashlee Simpson's darling son Bronx looked more than a little exhausted as she carried him through the LAX terminal after arriving from a long flight, on Friday evening.

The singer recently adopted a French bulldog puppy named Alabama for her 3-year-old, but the little guy has mixed feelings about the new member of their family.

"At first he was so excited, and then he was like, 'Wait! She's playing with my toys!' Now he is so in love with her. It's great," Simpson told People mag.

We bet Bronx can't wait till new cousin Maxwell is big enough to play with!

Mila Kunis was all wet and sweaty after an intense workout in LA on Friday afternoon, but she still looked amazingly hot!

The Black Swan star has been dating former That 70s Show costar Ashton Kutcher, and we spotted the pair enjoying a romantic date together at the Duplex Restaurant in West Hollywood the pervious night, after they went "public" at his Jobs wrap party last weekend.

Despite their constant relationship denial, it seems like the adorable pair are definitely more than "just friends."
