Hilary Duff

Hilary Duff took her 11-month-old son, Luca Comrie, to a Babies First Class in LA on Wednesday. She wore a loose tie-dye maxi dress, and he sported a "Hello, Ladies" shirt for the interactive mommy-and-me class, which the two have been regularly attending. While Hilary has been clocking in mom duty, she and husband Mike Comrie still find time to sneak away for couple's outings. They attended a Laker game last month and, more recently, the PGA Tour Wives Association 25th Anniversary event in Santa Monica, CA, on Monday. At the golf celebration, Hilary revealed that she's lost 30 pounds since giving birth to Luca in 2012. She credits the weight loss to a combination of circuit training and sculpting Pilates sessions.

While we all love cheering on our hometown teams, our favorite part of a basketball game is the opportunity to create the perfect sporty-chic look. And these two ladies — Katie Holmes and Katharine McPhee — both nailed it at the latest Knicks game. The dynamic duo covered all the fashion bases with chambray button-downs, distressed denim, punchy pumps, and a few glistening baubles. The result? Courtside styles that were equally polished and fuss-free. Whether you're heading to the game or just looking for a cool weekend combo, score big with these celebrity-approved looks.

The Lakers had plenty of star-studded support during their game against the Miami Heat at the Staples Center in LA last night, though they didn't take home a win. Hilary Duff took a break from mom duty with Luca to spend the evening out with husband Mike Comrie, while Mark Wahlberg and his wife, Rhea Durham, showed their boys love courtside. Leonardo DiCaprio hung out in the stands with a pal after making the rounds at Sunday's Golden Globes. It's been a busy week for the star since he was also spotted dancing at Bootsy Bellows on Tuesday. Other famous faces in the crowd included Ellen Pompeo, who cuddled up with her man, Chris Ivery, as well as Queen Latifah, Jack Nicholson, and Ron Howard.

Hilary Duff brought little Luca Comrie over to a friend's house for a playdate in Beverly Hills yesterday. The mother-of-one balanced a stylish Céline bag and her baby boy Luca in her arms as she crossed a grassy lawn in a pair of Rag and Bone booties. While those shoes are getting put to good use, some of Hilary's other pairs are being put towards a good cause. Several pairs of Hilary's autographed heels were put up for auction on Ebay recently, and she promoted the listings on Twitter with the hashtag #KickUpYourHeels. Money raised from the fundraiser will help support children's workshops and programs at the Lancaster Opera House Theatre in New York. Other celebrities getting on board include Kelly Clarkson, Brittany Snow, and Ashlee and Jessica Simpson.

Hilary Duff planted a big kiss on her little boy Luca Comrie's cheek on Sunday as she carried him into a Bristol Farms grocery store in LA. The affectionate mom and her hockey-player husband, Mike Comrie, stopped in to go shopping before celebrating their third holiday as a married couple and their first with baby Luca. Hilary paired a brown leather jacket with black booties and a high bun, while a giggling Luca sported stripes and a pair of baby New Balance shoes.

Hilary and Mike may be done having kids, according to a recent statement the mother of one made about their "perfect" little guy, but she still had plenty of holiday love to share. Hilary tweeted, "Happy Christmas Eve! Sending love and merry thoughts to everyone today! Big hugs and kisses!"

Hilary Duff carried her son, Luca Comrie, as they enjoyed an afternoon in Beverly Hills yesterday. Hilary wore black framed glasses and carried a navy and orange Marc by Marc Jacobs diaper bag as she balanced Luca on her hip. While Hilary doted on Luca during their recent outing, the new mom recently revealed that she might be done having kids. She said, "Mike [Comrie] and I are literally obsessed with Luca. We're like, 'He's perfect. We should just be one and done.'" Hilary's love for her little one might be why she is currently in second place to be named our favorite new celebrity mom of the year — don't forget to vote!

Hilary Duff took her baby boy, Luca Comrie, to another Babies First Class session in Sherman Oaks, CA, yesterday. Hilary had a huge smile on her face as a playful Luca crawled around with a pacifier in his mouth. The mother-son duo have been frequenting the class for new parents and babies, but Luca's attentive mom and dad have also been keeping up a busy social schedule.

Hilary and Mike Comrie came out to support Reese Witherspoon at the March of Dimes luncheon in Beverly Hills last week. Wearing a dress by Camilla and Marc, she posed with her husband and socialized with fellow new moms Elizabeth Banks and Megan Fox. Hilary has continued to focused on fitness these last few months, but a toned figure isn't the only appearance-related revelation the actress can be proud of. Hilary posted a picture of her new, extension-free hair, crediting her luscious locks to prenatal vitamins.
