Although it may be anyone's guess who Demi Moore was referring to when she finally broke her silence via Twitter on Thanksgiving Day, all signs point to soon-to-be-ex-hubby, Ashton Kutcher.

Moore, who so far appears to be keeping the "@mrskutcher" moniker, shared via Twitter yesterday:

"Why do we have only 1 day for giving thanks? Is that why so many people feel unappreciated? Make this 1 of 365 days of Thanksgiving!"

Ouch.

It's unclear who the 49-year-old star is spending her holiday with -- Rumer, Scout and Tallulah are in Paris with dad Bruce Willis.

Meanwhile Ashton had a more light-hearted Tweet for fans this holiday: "I’m thankful for family, friends, you, & time to reach my potential. What are you thankful for?"

It was only a quick appearance, but Cameron Diaz stole the show in her ultra short LBD as she surprised Jay Leno during his "Ask Jay" segment on The Tonight Show Thursday.

The 5'9 stunner also donned a pair of sexy $1,500 gold Lanvin platform wedge, to give her even more height!

While the Bad Teacher star recently split from New York Yankees baseball player Alex Rodriguez, she has reportedly moved on with an even bigger high-profile guy.

Cammie has been spotted getting cozy with none other than rapper/mega-mogul P. Diddy, and the pair were even seen looking all lovey-dovey over lunch together at Scarpetta in Beverly Hills last week -- is there a new Hollywood power couple on the rise?

Check out Diaz's show-stopping appearance on Leno at @ the 4:40 mark!

Justin Bieber has teamed up with old school R&B group Boyz II Men for the new single "Fa La La" ... off his new album Under The Mistletoe.

The black and white video shows a very grown-up looking Bieber dancing and singing alongside the foursome. The "Baby" singer has admitted to being a fan of Boyz II Men since he was a little kid. Wait ... isn't he still a kid?

Wanya, one of the four members of the band, recalls a funny story involving Bieber and their 90s hit song, "I'll Make Love To You." He tells MTV News:

"[Justin] told us his mum didn't want him to sing I'll Make Love to You, so he'd sneak and go sing it somewhere."

Awkward! Despite the very adult lyrics, we have a feeling Biebs sounded phenomenal!

Jessica Alba and hubby Cash Warren were all smiles while shopping at Trader Joe's in Beverly Hills for ingredients to make their big Thanksgiving feast.

While baby daughter Haven stayed in the stroller, 3-year-old Honor was eager to grab groceries off the shelf for mom and dad.

The Fantastic Four actress recently told Us Weekly:

“It’s really exciting this year because I have two little munchkins so I am really trying not to spoil them too much. But it’s hard because I loved Christmas even before I had kids!”

Such a sweet family of four. This is what the holiday season is all about!

Eva Mendes is spending her Thanksgiving holiday on the set of her upcoming film Holly Motors in Paris, and we can't help but notice how much her on-set look resembles the late singer Amy Winehouse.

The flick, now filming at Pere Lachaise cemetery in Paris, is being directed by Leos Carax ... and also stars singer Kylie Minogue.

As for the plot line, French actor Dennis Lavant plays a man who travels between different lives, including that of a murderer and scary creature. Mendes plays a character from his past.

By the looks of Eva's get-up, we're certainly intrigued!
