Look at those chubby little legs! And no, we're not talking about Miss Jones' lovely gams!

January Jones grabbed lunch at Little Dom's in Los Feliz Sunday with her adorable baby Xander, and we can't get over how big the tot is getting! As he gets older he looks less like his Mad Men mama, so he must be starting to resemble his father, whoever that might be...

The blonde beauty has kept the identity of her son's dad a secret since announcing her pregnancy last year, but we can't help but notice he looks a lot like Jason Sudekis, who the actress dated shortly before it was revealed she was expecting.

Just tell us already so we can stop the guessing game!

A famous actress that actually eats carbs?! We thought we'd never see the day!

January Jones hit up Trader Joe's in Los Feliz on Tuesday to grab some groceries, and we were shocked to see a baguette sticking out of her bag on the way out. We applaud the Mad Men star for not conforming to Hollywood's ridiculous weight standards. You go girl!

Once she checked marketing off her chore list, the blonde beauty headed to a local nail salon for some pampering. When you're a single parent and starring on a hit TV show, sometimes you just need a little "me" time!

It's a very special week for January Jones and her darling 8-month-old son Xander, because this is the actress's very first Mother's Day!

The Mad Men star looked casual and cool in bright red yoga pants that matched her son's shirt, a striped tee and sunglasses as she hugged her darling son close while making her way though Beverly Hills, on Sunday afternoon.

Jones has yet to reveal the identity of her son's father, but she seems to be enjoying her new role as a single mom!

January Jones looked like a walking optical illusion as she stepped out to host an exclusive screening of artist Yves Klein’s La Revolution Bleue at the Paris Theatre for Christie’s auction house in NYC, on Thursday evening.

Equally stunning, Victoria Silvstedt stopped traffic in her bright yellow skintight dress, paired with tan heels and light pink lipstick -- the perfect ensemble for a Playboy Playmate!

The Mad Men star was also given the honor of presenting the artist's painting, entitled FC 1, which is expected to sell for a whopping $30 million when it goes up for auction on May 8, with a portion of proceeds going to Oceana, the world’s largest international ocean advocacy organization.

Check out the $30 million piece of art, after the jump ...

January Jones isn't known for being the warmest gal in Hollywood, but we think motherhood has changed her... she's actually smiling!

The Mad Men star grabbed lunch with a friend in Beverly Hills on Wednesday, and not only did she look adorable in a polka dot sweater and a fedora, she couldn't hide her good mood on the way out. This is the January we like to see!

Maybe the 34-year-old actress is full of energy from eating her own placenta?! Whatever the case may be, we love seeing the blond bombshell in high spirits.

The only thing that would make us happier is to know who her baby boy Xander's daddy is! C'mon Miss Jones, spill the beans!

January Jones doesn't believe in wasting ... even when it comes to her own placenta!

The 34-year-old Mad Men star, who gave birth to son Xander Dane last September, has admitted to taking pills made from her placenta.

She tells People:

“I have a great doula who makes sure I’m eating well, with vitamins and teas, and with placenta capsulation. Your placenta gets dehydrated and made into vitamins. It’s something I was very hesitant about, but we’re the only mammals who don’t ingest our own placentas."

Jones has still not revealed the father of her son. As for eating her placenta, she adds, “It’s not witch-crafty or anything! I suggest it to all moms!”



January Jones and her adorable son Xander were spotted out and about in Los Angeles today, and is it just us, or does little Xander totally look like Jason Sudeikis?!

Jones gave birth to Xander in September 2011, and she was last linked to Sudeikis in early 2011, so as far as the timeline, it's definitely possible! There was recently a blind item suggesting Jones' former flame Ashton Kutcher was the father, but we don't really see much of a resemblance to the Two and a Half Men star.

And let's not forget about X-Men: First Class director Matthew Vaughn, with whom Jones had a "very close" relationship with on set, according to E! Online. Though Vaughn strongly denied any affair with the Mad Men beauty, he "abruptly" left town when she announced her pregnancy last April.

Jones STILL hasn't revealed who the daddy is, but as her little boy gets older, we're guessing someone is going to come out and say something, right?

It's time to buy a bigger nest!

Looking cool and causal in blue sweater, black jeans and comfy boots, January Jones took her 5-month-old son Xander (and his nanny!) shopping for a big new home in LA, on Friday afternoon.

The Mad Men star gave birth to her first child last September, and while she's not yet ready to reveal the baby daddy's name, she is anxious to leave her bachelorette pad behind!

Jones is currently in search of a home in an exclusive area of Beverly Hills that will be big enough to accommodate her growing family -- does this mean there might be more babies in her future?
