Jessica Simpson posted this shot of her three-month old son Ace on Twitter on Saturday, and we can't get over how cute the little boy is!

"With two kids, we have our hands full, but every day is a new adventure," Simpson told Us Weekly earlier this summer. "It's fun! I feel very at peace with being a mom."

The 33-year-old singer also revealed that having children with fiance Eric Johnson has only strengthened their bond. "My relationship with Eric has only grown stronger with the additions to our family," Jess told Hello Magazine. "I love seeing him as a dad. I feel like I reached a new level of love for him and I didn't think I could love him any more than I did ... Eric is incredible. I can safely say he has changed way more diapers than I have. Any time either of our babies needs anything, Eric is right there. I am so lucky to have him.''

Gwen Stefani could wear a burlap sack and still look amazing, but it looks like she's finally embracing the maternity clothes!

On Saturday the preggers singer and hubby Gavin Rossdale picked up son Kingston from soccer, and after that the family headed to a birthday party. We didn't see Zuma so we're guessing he was somewhere with the nanny, but they did bring their adorable Pomeranian Chewy:



Wonder if King and Zuma are getting a baby sister? Gwen still hasn't formally confirmed that she's expecting her third child, but given how much of her baby bump we've seen over the last few weeks, it seems pretty official!

Motherhood certainly looks great on Fergie Ferg! And we can't believe how quickly she got back into the skinny jeans and heels -- she gave birth just seven weeks ago!

Yesterday the 38-year-old singer left hubby Josh Duhamel home with their newborn son Axl, and she was in a great mood as she ran errands. The previous day the couple stopped by their new pad in Brentwood to check on the progress of construction, but it looks like it'll be a while before they can move in.

Reese Witherspoon grabbing a to-go bag from Le Pain Quotidien in Brentwood may not usually be headline news, but a CNN crew was there to document her everyday activities on Saturday morning. The Oscar winner is used to having her picture taken everywhere she goes, but why would CNN join the paparazzi crew?

Super Size Me documentary maker Morgan Spurlock is taping an episode of his show Inside Man about celebrity photographers and it appears his crew was scoping out Reese yesterday. Morgan was conspicuously absent, however ... Hey! Can't hang, Morg?

On Saturday night Katy Perry attended beau John Mayer's concert at the Hollywood Bowl, and she was joined by her BFF Shannon Woodward, her dad Keith and her sister Angela.

Afterwards John tweeted, "Fantastic show tonight and a great end to this leg of the tour. It was awesome having @Phillips with us. Really looking forward to the fall." Unless Katy plans on going with him to Europe this month, we're guessing she's not looking forward to spending a few weeks apart from him ... Then again, she's so busy promoting her new album Prism, maybe this is perfect timing?

Kelly Osbourne and fiance Matthew Mossheart landed at LAX on Saturday night, and the purple-haired starlet looked positively exhausted. Perhaps because she had been up all night on with her mom Sharon?

Yesterday Kelly tweeted, "My mum & I just worked a 24 hour day I'm so tired I feel like sh*t but it was so fun I feel like a d*ck for complaining!" The previous day she wrote, "My mum & I have been working on a project together for over 10 years today is the day it is finally happening! Cant wait 4 you guys to see!!"

Wonder what this secret project is?!

Miley Cyrus appeared on Saturday Night Live last night, and the 20-year-old starlet had an interesting run-in with the ghost of her past, who warned her about her scandalous MTV VMA performance.

For her opening monologue, Miley told the audience, "There's a few subjects we're not going to get into tonight ... I'm not going to do Hannah Montana, but I can give you an update on what she's been up to -- she's been murdered." Yikes! So what did she have to say about her VMAs performance?

Miles joked that she had received phone calls from both "angry mothers" and "turned on fathers," and she added, "I don't apologize for my VMA performance. If I owe anybody an apology its the people who make the bottom half of shirts."

Miley and company also did a spoof of the government shutdown set to her "We Can't Stop" music video, and not only was there twerking involved, but the singer donned a brunette wig and dressed up as a sexy Michelle Bachmann ... check it out below!

And she's back to covering up her left hand, so we can't tell if the ring is on again...

On Saturday Khloe Kardashian hit the gym near her home, and as usual she wore spandex and an oversize hoodie and had absolutely nothing to say when asked about whether she's planning on divorcing Lamar Odom. We know they had a chat last week, but she's also selling their home, so no one really knows the status of their marriage...
