Reese Witherspoon, 42, proves she's an ageless beauty as she was spotted in a pretty mini dress

She just turned 42 on Thursday but she has shown us time and again, how much of an ageless beauty she is.

Reese Witherspoon’s adorable 5-year-old son, Tennessee Toth, gave her a birthday cake to start off her birthday with a bang. The actress shared it on her Instagram and said she was having “cake for breakfast.” AmoMama collected the details from Daily Mail.

The blonde star then headed to a birthday lunch in Hollywood, looking chic in her coordinated blue outfit. She stepped out in a beautiful dark blue frock that featured a colorful floral pattern.

She also donned a matching shade of blue that was the same length as her dress as well as a pair of matching heeled ankle boots. Completing the look were her pair of owl-shaped sunglasses and a shoulder purse in the same blue color.

The Big Little Lies star also mentioned on her birthday post on Instagram that she was feeling the love from her friends and also got to plug in her line for Draper James, which she wore for the particular snap.

One of those friends that she felt the love from was Jennifer Garner, who was one of the first celebrities to wish her a happy 42nd birthday. In her post, she played 'Happy Birthday' for the Legally Blonde actress.

Nicole Kidman also posted a photo of the two of them to Instagram. She called Reese “a friend, a partner, a leader, and an inspiration.” She also wrote:

“And you make me laugh like nobody else. Happy Birthday Xx [heart emoji].”

Reese’s Wrinkle In Time co-star, Minda Kaling, also took to Instagram to greet her and so did Zoe Zaldana, who wished her a happy birthday on Twitter and her IG story.
