Leann Rimes is having quite the busy week!

Besides planning a 39th birthday/Father's Day party for hubby Eddie Cibrian this weekend, the "Bonus Mom" also helped get her stepson ready for his preschool graduation luau, on Wednesday afternoon.

Rimes revealed via Twitter: "Up making lunch for lil bit's last day of preschool. He has a luau today....his outfit is FABULOUS if I must say so myself. He's rocking."

It's anyone's guess if Cibrian's ex-wife Brandi Glanville will be attending the weekend festivities, but it looks like smooth sailing with LeAnn, who shared a Twitpic of her stepson, with the caption: "Had to share his luau fabulousness!!!!! Mom and he are gonna rock out today. @brandiglanville have Fun!"

Adorbs!

When you're Gorge Clooney's latest main squeeze, the perks are endless!

Stacy Keibler couldn't stop smiling as she treated her girlfriends to a boat ride on Italy's Lake Como on Wednesday afternoon, where she's currently vacationing with her Oscar winning beau at his luxurious $20 million Villa, in the town of Laglio.

The WWE star showed off her endless legs in sexy red shorts, a white tank and a pretty matching scarf as she took in the scenery with her galpals, but it looks like George opted to sit this one out!

The happy couple were seen taking a romantic ride on his boat early this week, before enjoying a shopping spree at some exclusive boutiques in the area -- talk about a dream vacation!

When you're Simon Cowell, you can never have too many luxury cars!

The mega music mogul was looking to add a new hot rod to his massive collection of expensive rides, and he took a break from filming X Factor to visit a Porsche dealership in Beverly Hills, on Wednesday afternoon.

Things have been a bit stressful for Cowell since he began shooting the second season of The X Factor with new judge Britney Spears, and it's been reported that the pop star has walked off the set so many times, he's beginning to regret ever hiring her!

Britney is reportedly earning $10 million for her new gig, but she was accused of being "unprofessional" after leaving her seat on her first day of filming in Austin, Texas. Spear's manager Larry Rudolph insists, "Everything is fine, Britney loves being on X Factor." If Brit's antics are actually just a publicity stunt to give the show more hype, it's definitely working!

Ashton Kutcher was spotted shooting scenes at Steve Jobs' former childhood home in Los Altos, California this morning, and the 34-year-old actor was joined by co-stars Ahna O'Reilly, Josh Gad and Lukas Haas.

According to reports, this should be the last day of filming in NorCal, and production is expected to move to Los Angeles tomorrow.

Dermot Mulroney was also snapped on set today, and we're not sure who he's playing, but he was wearing quite an impressive suit:

She's due to give birth any day now, so it makes sense she would want to rock comfy workout gear!

Kourtney Kardashian kept busy filming her reality show in Studio City today as she awaits the arrival of her baby girl, and the 33-year-old looked amazing for being nearly nine months pregnant! Black is slimming, but we can barely spot a baby bump!

We happened to notice that Kimmy K's big sister appears to be a sporting an wrist brace... did she sprain it trying to pick up Mason? Luckily her other hand was injury-free to carry a folder of makeup samples... we bet she's choosing shades for the sister's new makeup line Khroma beauty!

Maybe the family's ever expanding empire is why fellow mogul Oprah Winfrey stopped by their Calabasas pad for a sit down interview recently? The talk show queen posted this pic of her posing with the whole clan to her Facebook page, with the chat session airing on Oprah's Next Chapter on Sunday on OWN.

Robert Pattinson and Kristen Stewart are finally a family ... at least on the big screen!

Edward and Bella Cullen are gracing the cover of Entertainment Weekly alongside their vampire daughter Reneesme.

Although twi-hards are probably going to go nuts for this issue, we find it a little interesting that the girl has already passed her toddler years.

Mackenzie Foy, who plays Reneesme in The Twilight Saga: Breaking Dawn - Part 2 is no doubt, thrilled with the casting. What a lucky 9-year-old little girl!

Ouch! Looks like someone spent a little too much time at the beach last weekend!

Despite her sunburn, Hilary Duff was all smiles when we snapped her running errands in Beverly Hills this afternoon. The new mom showed off her slimmed-down figure in a pair of black skinny jeans and a print top, and she may not be back down to her pre-pregnancy physique, but she's obviously been busting her booty at the gym and Pilates! Maybe she could give Jessica Simpson a few words of encouragement?

While Hil doesn't look one bit frazzled in these shots, she's definitely still adjusting to motherhood! Earlier today she tweeted, "It's pretty much impossible to be on time when you have a baby..."

We see you working on your fitness girl!

Earlier today, cameras spotted the Friday Night Lights star going to Equinox gym in Century City looking ready to sweat!

It's summertime so it only makes sense that Minka's keeping herself in tip-top shape. It could be for a new role or better yet a new man?!
