Reese Witherspoon Poses With Her Kids: 'I'm Lucky To Be Their Mom' [Photo]

Reese Witherspoon, who recently celebrated her kids' return to school with a dance video, took to Instagram Saturday to share a photo of herself and her two oldest kids.

The 45-year-old actress shared a snap featuring herself sitting in the middle and her two kids, 21-year-old Ava and 17-year-old Deacon, whom she has with ex-husband Ryan Phillippe.

In the photo, the actress, who was make-up-free, could be seen smiling sweetly for the camera. She wore a black top while her daughter Ava donned a grey sweatshirt and Deacon wore a plain white t-shirt, which he paired with a tan-colored cap.

"Gosh, I'm lucky to be their mom," the mother of three wrote. The actress also shares Tennessee James Toth, 8, with her husband Jim Toth.

The photo has so far been liked not only by fans but also by fellow celebrities, including actress Drew Barrymore. Many of them even left comments praising the actress.

Actor David Burtka commented, "They are lucky to have you!!"

Candace Nelson, judge of the "Cupcake Wars and Sugar Rush" television series, wrote, "This fills my heart!"

Cindy Crawford commented, "You look like their sister!"

Meanwhile, singer Holly Williams also pointed out how young-looking Witherspoon was, writing, "Literal sister."

The post came a day after the actress appeared on Dax Shepard's podcast, "Armchair Expert," which was hosted by Monica Padman and Kristen Bell.

During her guesting, Witherspoon reflected on raising her first baby, who was born two months after she got married to Ryan Phillippe in 1999. She then welcomed Deacon in 2003 and got divorced from Phillippe in 2006.

"I did not have a lot of support with my first baby and I learned really early, like this is not going to work," she explained. "I tried to muscle through for five months with Ava, just not sleeping and I became delirious."

On the work front, the actress will be next seen in the movie "Your Place or Mine," which is directed by Aline Brosh McKenna. She will also feature in "Legally Blonde 3," "Wish List" and "Tinker Bell." She lent her voice to "Sing 2," which is slated for release on Dec. 8.
