Just because it's December, don't expect Matthew McConaughey to give his cardio routine a break!

We spotted the 42-year-old actor leaving the gym yesterday, and while he wasn't frolicking around on the beach without his shirt on, he still looked pretty handsome! Matty sported one of his j.k. livin beanies, and we have to say, it's good to see a celeb actually promoting their own company.

Ashton Kutcher drove around Hollywood yesterday and eventually stopped at an aerial viewpoint to admire the city, and the actor looked totally heartbroken when he stepped out of his Lexus. Not only was Ashton's wedding ring off, but he's also removed his Kabbalah bracelet ... is it possible he's given up on the religion now that Demi Moore has given up on him?

After Ashton allegedly cheated on Demi with 22-year-old Sara Leal, the couple sought private counseling through the Kabbalah Centre, and they even went on a camping retreat with instructor Yehuda Berg in an attempt to save their marriage. Demi has a much longer history with Kabbalah, so perhaps Ashton is trying to get rid of any reminders of Demi and finally move on with his life.

While the Two And A Half Men star looks lost and despondent in these photos, his tweets have been pretty cheerful as of late. The other day he wrote, "Need some #Christmas shopping ideas? May I suggest a yodelling pickle?" and he hasn't made any cryptic mentions of his failed marriage.

Yesterday we spotted Ludacris at the Ferrari dealership in Beverly Hills getting some custom touches put on his new car, and the rapper appeared stoked to be in charge of the vehicle's mini-makeover.

So what else has he been up to? After dropping his new music video for "Rich & Flexin", Luda went out to celebrate, and he tweeted, "Damn Cali medicinal treats got me thinking Im in the club taking pics wit Elmo. Wtf! #whatusmokingon." Ok then!

Dressed in a bow tie and sexy cat-eye sunglasses, Kourtney Kardashian dodged throngs of photogs while making her way to lunch with partner Scott Disick, on Friday.

The newly-preg reality star kept mum when asked about the sex of her baby, but she was very vocal today via Twitter.

When MTV Teen Mom star Farrah Abraham blasted the Kardashian sister on her official page with the Tweet: "Im Shocked Kourtney Kardashian is pregnant again, Did she not learn anything from TEEN MOM? Maybe its a fake pregnancy like kims wedding SAD."

Kardashian was quick to respond to the insult, Tweeting: "Why would I have anything to do with Teen Mom? I'm 32 years old! I may look young, honey, but don't get it twisted."

Scott Disick added, "We're not teenagers, ya f**king moron," while outspoken Khloe also got in on the action, Tweeting: "I just thought she was some sh*t stain on Twitter, no? ... I've never met a better mother than Kourtney."

Don't mess with the Kardashian clan!

After suffering though the painful loss of her ex-husband Russell last summer, Taylor Armstrong has just signed a book deal with Simon & Schuster which will follow the reality star's turbulent life thus far.

The Real Housewives of Beverly Hills star will share photos and details of the physical and emotional abuse she suffered at the hands of her ex, who committed suicide in the bedroom of a friends Mulholland Drive home on August 15.

The memoir will recount not only Taylor's own personal experiences with abuse, but also highlight several celebrities who have been involved in similar domestic situations.

Armstrong is hoping the book will help educate other victims of domestic violence -- she filed for divorce in July, citing domestic abuse.

The yet-untitled book is set to hit shelves on Feb. 7.
