Reese Witherspoon went shopping at Paper Source in Beverly Hills on Monday afternoon, and the Oscar winner was all smiles when we spotted her on the way out. We love that she's always in such a good mood!

Whether she's running errands, busting her booty at the gym or spending time with her children, it seems like Reese is always on the move. And in the next few moths, she'll be getting back to work with not one but four different film projects!

In addition to promoting Devil's Knot and Mud, she's set to begin shooting on Men Are from Mars, Women Are from Venus, Wish List and Big Eyes in 2013, she she's in talks to star in the 2014 flick The Good Lie, which "centers on a young refugee of the Sudanese Civil War who wins a lottery for relocation to the U.S. with three other lost boys," according to The Hollywood Reporter.

The wind may have gotten the better of her dress, but Reese Witherspoon was all smiles when we spotted her waiting to cross the street in Brentwood on Friday.

Earlier in the day the Oscar winner hit the gym, and we got a peek at the background on her iPhone, which is an adorable shot of her baby boy Tennessee. Aww!

While Reese has been on supermom duty lately with all three of her kids, she will be getting back to work this year on several projects. In addition to Devil's Knot and Mud, and she's set to begin shooting on Men Are from Mars, Women Are from Venus, Wish List and Big Eyes in 2013.

Reese Witherspoon and husband Jim Toth were snapped in Santa Monica on Tuesday, and we got a peek at their their adorable son Tennessee. What a cutie!

Reese skipped out on the SAG Awards and the Golden Globes this month (instead she was at Sundance to premiere her new film Mud), but just four months after giving birth to her third child, she's already getting back to work!

In addition to Mud, she'll also be promoting Devil's Knot, and the Oscar winner's next two films, Wish List and Big Eyes are currently in the pre-production phase. Reese is also reportedly in talks to star in The Good Lie, a film that follows a young Sudanese refugee who relocates to America, and she'll also star in Men Are from Mars, Women Are from Venus in 2014. Busy mama!

Reese Witherspoon has a great sense of humor!

The Oscar-winning actress, who gave birth to son Tennessee last September, left her morning workout sporting a mustache t-shirt. Adorbs!

We love that the 36-year-old mama of three doesn't mind showing her pretty face even without makeup.

Who can resist that A-list smile? What a beauty!

Is she feeling a little shy?

On Saturday, Reese Witherspoon ditched her usual street style when she stepped out in a hooded jacket and pink sweatpants to hit the gym in Los Angeles.

Afterwards, the 36-year-old actress ran errands in Brentwood while rocking the same 'fit along with a Gatorade towel, presumably from her workout. Sometimes dressing down is the way to go!

On Thursday afternoon we spotted a chipper Reese Witherspoon running errands in Brentwood, and the Oscar winner flashed us a quick smile before returning home to her three kids.

After taking a break from films following the birth of her son Tennessee, Reese will be back on the big screen this year with Devil's Knot and Mud, and she's set to begin work this spring on Men Are from Mars, Women Are from Venus, Wish List and Big Eyes.

The trailer for Mud hit the web this week, and Reese stars as Matthew McConaughey's long lost love in the film. The flick follows two teenage boys who come across a fugitive (McConaughey) and promise to hide him from bounty hunters and reunite him with his lady (Witherspoon). Check thru to watch the teaser!

A lot of kids look like their parents, but this is on a whole other level!

Reese Witherspoon and her children Ava and Deacon were out and about in Hollywood yesterday, and for a second we thought we were seeing double! The Oscar winner and her daughter look identical!

We wonder if the preteen likes being compared to her famous mom? For Reese, the comparisons are probably super flattering!

Speaking of flattering, the bubbly blonde recently showered fellow actress Naomi Watts with praise for her performance in The Impossible, which earned her an Oscar nomination.

"Not since I saw Meryl Streep's performance in Sophie's Choice have I been so moved by an actress's performance. It reminded me of Sally Field's Norma Rae as well. Such strength an absolute vulnerability in the same performance. A mother who is determined to teach her child what it means to be a good person even when facing her own mortality. You showed every side of Maria's story," she wrote in a gushing letter to the Aussie film star.

We love women supporting other women in Hollywood!

Reese Witherspoon was spotted arriving at her yoga class in Santa Monica on Wednesday morning, and she's laughed off reports that she's lost all of her baby weight after giving birth three months ago.

"I don't know if I'm bouncing back. I'm slowly crawling back," the Oscar winner told Extra last month. "You know, all of your joints feel wobbly, and your head is sort of confused ... You just have to be gentle and patient with yourself and just sort of, you know, slowly get back to your health."

Sounds like a good plan!
