Reese Witherspoon went bowling for her birthday.

The 'Legally Blonde' actress celebrated her 38th birthday on Saturday night (22.03.14) with her mother and a group of close friends at a bowling alley in Nashville, Tennessee.

The mother-of-three - who has 14-year-old daughter Ava and 10-year-old son Deacon with actor Ryan Phillippe, and 17-month-old son Tennessee with her husband Jim Toth - seemed to be having a blast as she posed for pals to document her attempts at bowling a strike.

She wrote on her WhoSay account: ''Having a ball at my birthday! #nashvegas#goodfriends#bowlersnotballers''.

Reese also shared an adorable selfie of her smiling alongside her mother Betty, thanking her for her support over the years.

She posted: ''Thank you to my amazing mother! #happybirthday#9months#birthandbeyond''.

The star kicked off her acting career age 12 in Tennessee and has spoken openly in the past about how grateful she is that her parents kept her grounded as a teenager.

She said: ''Thank God my parents did this, but they told me I had to stay in school. I was allowed to work in the summers but I couldn't work in the school year. They said, 'You're not moving to California, that's where crazy people live'.''
