Joel was on coffee duty while Nicole pushed Harlow for their family errands around LA on Thursday. We got a great dose of that little baby this week as the new mommy gears up for her first Mother's Day tomorrow. From the way she gushes about her daughter, just having Harlow seems like gift enough but I'm betting that sweetheart Joel has something special planned for the lovely ladies in his life.

Britney will be making her second guest appearance on How I Met Your Mother on Monday, and it will be interesting to see if she can hit another ratings homerun the second time around. Most of you loved her first appearance, so watch the cute teaser for Monday night's episode and tell us - will you tune in to see Britney again?

Lauren Conrad had her hands full with her coffee, suitcase, and more as she headed back to her villa in LA, fresh off her trip to the MTV Upfronts in NYC Thursday night. This girl is used to globe-trotting by now, and we doubt she let a little jet lag slow her down since Friday was Audrina's 23rd birthday. Things might be a little awkward between these two BFFs now that Lo is part of the house, but we all know that a little birthday drama could make for a great episode for the next season of The Hills.

Now that Isla is filming Confessions of a Shopaholic down in Miami, it's time to break out the warm weather gear. She still managed to look gorgeous in her latest quirky ensemble as she multi-tasked on her BlackBerry while getting her hair done yesterday, but cutie Olive had to wait in the wings for her mom this time. She probably didn't go very far - these two have a Mother's Day to celebrate on Sunday.

Maggie Gyllenhaal and Peter Sarsgaard took their confident little walker, Ramona, out for a stroll in Brooklyn yesterday. Looks like the little one is already getting into the spring spirit in her pink dress - how much does she look like both her parents? Kinda incredible. As big as she's getting, Ramona is still a bit too little to check out her mama's big summer movie, The Dark Knight. Speaking of which, have you seen the new trailer? Creepy and awesome. While Maggie's movies may be on the adult end, her charitable side is good for any age. She teamed up with Real Simple and Design on a Dime for their annual charity event. Sweethearts of all sizes in that family.

After slipping into a sexy black gown at the Costume Institute Gala on Monday, Fergie kept the party going at the Waverly Inn last night. She must have really enjoyed herself because she looks like she took a tumble in her high heels as she headed out into the streets of NYC. Luckily, Fergie is no stranger to a little clumsiness and shook it off with a smile on her face.

Rihanna and Chris Brown were caught sharing a romantic private moment in their friendly local KFC while in Miami last night. What can I say - sometimes you're just in the mood for some fried chicken to go with your PDA. Also, maybe I'm reading too much into these candid photos, but does she seem more into it than he is? That is just not right; she is so the catch! Just saying. Rih recently admitted that she and Chris brown are "very close now", so maybe it's only a matter of time before these secret lovey moments in pools and clubs become a little more public. Hope so.
