Reese Witherspoon Wows In A Chic Mint Green Dress On The Red Carpet After Ex Jim Toth Reportedly Moves On

Reese Witherspoon graced the Oceana annual Sea Change summer party red carpet in a chic, strapless, mint green dress that highlighted her curves and toned figure.

The Oscar winner, 47, brought her lookalike daughter Ava Phillippe, 23, as her date to the event. On July 23rd, the Legally Blonde alum shared behind-the-scenes shots of them both getting ready for her Instagram followers.

This appearance came just after People Magazine disclosed that Witherspoon’s former spouse Jim Toth was seen in Costa Rica with a new girlfriend. Witherspoon and Toth had been married for close to twelve years before they announced their split four months ago.

The Big Little Lies star’s dress featured a waist-cinching fit, an eye-catching light green hue and flirty strapless neckline. Her daughter wore a similar ensemble, composed of a strapless, cinched white top and matching maxi skirt.

While Witherspoon chose to go for a minimal look when it came to accessories, Phillippe added a black choker necklace. They both wore their long blonde tresses down, styled into elegant, loose waves.

The Cruel Intentions actress also wore her new wispy curtain bangs down, drawing eyes to her makeup look. Witherspoon rocked smokey eyeshadow, thick black liner, voluminous mascara, rosy blush and a glossy pink pout. Her daughter twinned with her and played up her eyes and high cheekbones as well.

Witherspoon shared a three-part IG slideshow post for her 29.6 million followers, showing fans how she and Phillippe got ready for the soiree in the first pic, the products they used in the second and a beautiful mother-and-daughter red carpet pic for the last slide.

The Sweet Home Alabama alum captioned her upload: "Perfect Summer night with my girl @avaphillippe, learning all about @oceana incredible conservation work #BiossancePartner."

Naturally, fans hyped up her and her daughter's looks in the comment section, deeming their ensembles and glam to be "stunning," "gorg" and "timeless."

Witherspoon's Ex Jim Toth Reportedly Spotted With New Flame in Costa Rica

Witherspoon and Toth surprised many fans back in March when they announced they were divorcing after almost 12 years of marriage.

A source recently dished to People Magazine last week that Toth is currently dating someone new. "Jim was staying with a new girlfriend at the Sendero Nosara in Costa Rica," an onlooker reportedly told the outlet.

"They seemed to be staying in a suite, and they looked really happy, just chilling and soaking up that pura vida vibe. It was definitely romantic."

Four months ago, Witherspoon and Toth released a joint statement, confirming their decision to split after rumors began circulating online. They noted that their choice to divorce was a "difficult" one made with a "great deal of care and consideration."

The former couple continued: "We have enjoyed so many wonderful years together and are moving forward with deep love, kindness and mutual respect for everything we have created together." Witherspoon and Toth share a 10-year-old son, Tennessee. They tied the knot in March 2011 in a laid-back wedding on the Your Place or Mine star's ranch in Ojai, California.

Witherspoon also shares two children; daughter Ava, 23, and son Deacon, 19 with Ryan Phillippe, who she was married to from 1999 to 2008.

In a candid interview with Harper's Bazaar this month, Witherspoon opened up about her split from Toth.

"When I was divorced before, the tabloid media got to tell people how I was feeling or how I was processing, and it felt very out of control," she told the outlet.

She added: "To be able to talk to people directly about what’s going on in my life and just share it in the way that I share great professional experiences or personal experiences, it feels much more authentic to be able to say things in my own voice and not let somebody else control what’s happening."

The Draper James founder continued, noting that she is at peace with her current state: "It’s a liberation in your 40s to feel free of other people’s opinions. I mean, they’re always there. They just don’t matter as much to you, and it’s a great feeling."
