Yesterday Kim and Kourtney Kardashian went to church in Calabasas, and Kourt carried newborn daughter Penelope while Kim was on auntie duty with little Mason. As always, the ladies looked amazing, but we have to wonder what fellow churchgoers thought of Kim's sexy shoes?

On Saturday Kim tweeted, "Slumber party with Mason and Penelope!" and the next morning she tweeted the above photo of Kourt in the kitchen and added, "I woke up this morning to this ... gotta love @KourtneyKardash making breakfast."

In addition to attending a baby shower, bonding with her sister, shooting footage for their reality show and saying a few prayers, Kim also spent some time at a fitting and she tweeted a photo of several bikinis on Saturday and wrote, "Packing for something fun!!! Can't wait to share..."

Hmm, could it be another vacation with Kanye? You know, the one where he proposes?

Fergie and Josh Duhamel went to brunch on Sunday in Los Angeles, and the singer concealed her stomach under a baggy top and a floppy leather vest. While she could be going through a concert t-shirt phase (last week it was Journey and the Ramones, this one's emblazoned with the Iron Maiden logo), we do find it interesting that a) everything she's been wearing has been a bit loose and b) Fergie and Josh went to a medical center in Beverly Hills last week, causing further speculation that they're planning for a baby.

Of course, last week she tweeted a photo of herself at a Voli Spirits party (she's a co-owner and spokesperson for the vodka company), and she's seen holding onto a bright red drink in a martini glass. Any chance it was a virgin cocktail or is all this baby blabber completely bogus?

Jessica Alba is finally beginning production on Sin City: A Dame to Kill For, and the 31-year-old actress tweeted some photos over the weekend of her new hair ... and her killer prep work for the sequel!

"Stage 2 of #SinCity2 Nancy hair ... She got roots that Nancy," she wrote. "What a way to start the day - training for a movie is sorta fun."

The follow-up to Frank Miller and Robert Rodriguez's 2005 hit follows Dwight (previously played by Clive Owen) as he "plans to have his vengeance against the woman who betrayed him, Ava Lord, while Nancy is trying to cope with Hartigan's death," according to IMDb. Can't wait to see where this goes!

Now THAT'S an odd couple!

Rihanna went on a date with Rob Kardashian Saturday night -- and though it started with a pretty innocuous trip to Racer's Edge Indoor Karting in Burbank, it ended at Playhouse nightclub in Hollywood!

Just a week after Rihanna's self-expose on Oprah's Next Chapter, in which the singer said she still loves Chris Brown despite his arrest for physically assaulting her in 2009, RiRi stepped out with the least famous Kardashian.

This isn't Rob's first foray into dating hot pop stars ... the reality show star was dating UK's Rita Ora not too long ago and even went on a double date with his honey and sister Kim Kardashian and her beau Kanye West in May.

You think Rob and Rihanna could last or will Ri race away from Rob as fast as you can say Chris Brown?



Having three kids under the age of 7 is no small task!

But Ben Affleck and Jennifer Garner are doing a bang-up job and parenting their two girls and baby boy. The couple took all three for ice cream Saturday in Brentwood ... though it looks like Sam left with just a rattle rather than a double scoop.

Even though Ben's in the middle of filming Runner, Runner, most of which takes place in Puerto Rico, the actor is taking time off to be with his family ever chance he gets.

Affleck stars in two other films coming up -- Argo, which he also directed, due in theaters this October; and To The Wonder, which is set for release before the end of the year.

Chris Brown was hard at work Saturday on the set of The Game's music video of his new single "Celebration."

The song features Wiz Khalifa, Tyga and Lil Wayne and will showcase lots of classic lowriders in addition to the all-star cast.

Brown appeared to be in good spirits after his ex's tell-all interview with Oprah in which Rihanna admitting to still being in love with Chris despite his 2009 assault against her.

Rihanna claimed he "made a mistake" and "needed help." Brown was reportedly upset at Ri for reviving her memories of the incident on national television. Hmmm ... guess there are some things you just can't live down ...

Hilary Duff took son Luca Cruz, 5 months, to her local farmer's market for some coconut milk and fresh produce.

Back in June, Duff said she was "working hard" to lose the baby weight but "doing it the right way ... not too drastic." We spotted her sipping from a fresh coconut Saturday and weight loss experts say this could be a great way to drop those extra pounds. Coconut water is the perfect way to hydrate with just the right amount of natural sugar and actually increases the body's metabolic rate.

Well Hil's on her way and looking great and she's got one adorable baby to show for it!

Britney's ex, Kevin Federline, and her fiance, Jason Trawick, were apparently trained to do grocery shopping ... we've gotta hand it to Brit for getting these guys to participate in domestic duties!

Meanwhile, KFed's got other dooties to deal with. He's got a year-old baby with girlfriend Victoria Prince.

Perhaps the question is ... which couple will beat the other to the wedding chapel? Jason and Britney are engaged, but recent reports claim their engagement is on the rocks and Brit may be having second thoughts.

Spears is busy taping American Idol and after not working for so many years, perhaps the stress of her hectic show schedule is getting to her?

As for Federline, he hasn't even popped the question to Prince. Better get a move on, KFed!
