Hmm, who knew Liam Hemsworth was a secret smoker?

On Sunday we spotted the Aussie actor driving fiancee Miley Cyrus around Studio City, and we couldn't believe that he was puffing away inside of her Mercedes SUV! Maybe she smokes inside her pricey ride too so she doesn't mind the smell?

The lovebirds went on a Starbucks run, and we're not sure where they were headed but they had about 8 beverages with them -- maybe this was for the entire Cyrus family?

Looks like the rumors are true that Charlie Sheen's ex-wives Denise Richards and Brooke Mueller are quickly becoming BFFs!

On Sunday afternoon we spotted Denise with daughters Sam, Lola and Eloise, and she was also joined by Brooke's twins, Bob and Max. Later we spotted Denise and Brooke together at the Cross Creek shopping mall in Malibu, and it appears as though they did lunch with their five young children.

Charlie recently chose Denise to appear on his new TV series Anger Management, and he said in an interview about her casting, "She is still a knock out and that's what the part called for, and I can deal with her directly not through her agent, which was good." Charlie added, "She looked great and it was fun to do that in front of our children, get them to see what their parents do for living, what pays for all those toys!"

Pete Wentz and Meagan Camper were snapped at the Farmers Market in Los Angeles on Sunday, and the hipster couple drank matching Starbucks and held hands as they checked out the flowers and groceries.

While this is pretty cute and all, we couldn't help but notice Pete's shirt with some rather strategically placed teddy bears. Since ex-wife Ashlee Simpson is back in town, it looks like she had Bronx over the weekend, so she won't have to worry about their 3-year-old son seeing any ahem, incredibly inappropriate t-shirts!

Blake Lively and Ryan Reynolds have tied the knot in a surprise private ceremony at Boone Hill Plantation in Mount Pleasant, South Carolina, according to multiple reports.

Lively's family were spotted around Charleston, along with close pal Christian Louboutin. Lively and Reynolds have also traveled to Charleston several times over the past year, so many began to speculate that the lovebirds were choosing the city as a wedding spot.

The actors met while filming The Green Lantern in 2010, and by late 2011 they became romantically involved. Lively previously dated her Gossip Girl co-star Penn Badgley, and in the summer of 2011 she was linked to Leonardo DiCaprio. Reynolds was engaged to Alanis Morissette from 2004-2007, and his marriage to Scarlett Johansson lasted from 2008-2010.

While their nuptials come as a bit of a surprise, the couple did purchase a house together in Westchester County, New York after 6 months together, so it's not that shocking, right?

Even though she's wearing a baggy shirt, it sure looks like she's dropped quite a few of the pounds she gained during her pregnancy with daughter Maxwell!

Jessica Simpson was spotted at JFK International Airport on Sunday afternoon, and the 32-year-old singer/actress will make her first public appearance since giving birth on Katie Couric's new TV show tomorrow morning.

Last week, Simpson revealed that she was 10 pounds away from her pre-baby size, but there's some debate as to what exactly that weight is. Jess weighed in at 170 pounds in March, and after giving birth to daughter Maxwell in May, she reportedly tipped the scales at 210 pounds, but that estimate seems a bit on the uh, heavy side. Still, she is proud of her progress. "I'm not a supermodel," she told USA Today last week. "My body is not bouncing back like a supermodel. I'm just your everyday woman who is trying to feel good and be healthy for her daughter, her fiance and herself."

Can't wait to see her big Weight Watchers reveal later this week too!

Kourtney Kardashian arrived at LAX on Sunday with son Mason and daughter Penelope on Sunday, and even though baby daddy Scott Disick was nowhere in sight, the reality star didn't seem to mind!

Kourtney recently shocked her family when she stated that she was going to stop taking birth control, adding that she wanted to have around 6 kids! Scott, who is an only child, thinks two is enough (he protested, “I don’t want to be outnumbered by my children"), but it looks like Kourt will have her way!

Watch the teaser clip for tonight's episode below:

After attending her fashion show in NYC, we spotted Victoria, David and little miss Harper Beckham grabbing lunch together at Balthazar.

Victoria debuted her Spring/Summer 2013 collection at the New York Public Library, and after the show she tweeted, "Relieved!!! Can't believe it's over. Thank you #vbteam!!! #vbss13 #nyfw X vb." The former Spice Girl received rave reviews for her latest line, and though she stuck with mostly monochromatic outfits, she did add a pop of color to some of the clothes with red, and there was plenty of texture as well.

Posh teamed up with Stephen Jones and Manolo Blahnik for hats and shoes, and her hunky hubby sat front row and snapped photos of his lady love at the end of her show. We love the fact that he's so supportive!

What a great way to spend your weekend!

After flying back in from NYC on Friday night, Gwen Stefani and sons Kingston and Zuma were up early on Saturday to hit the minature golf course in Sherman Oaks. While Kingston had a blast swinging away, Zuma seemed to have more fun watching his big bro than trying to hit a hole in one.

Gwen has been busy prepping for the release of No Doubt's new album, Push and Shove, and she brought her sons with her to the Big Apple for the 2012 NFL Kick-Off concert last week.

So what does she have to say about balancing motherhood and her other career endeavors? Gwen reveals in the new issue of Elle UK that she regularly skips her L.A.M.B. fashion events because she needs to be around to take care of her boys. "I’ve missed the last couple of fashion weeks because of school," she says. "I can’t leave the kids, I can’t miss the first week of kindergarten. I just can’t.”
