Jennifer Garner is seen filming after ex Ben Affleck tied the knot with Jennifer Lopez

Jennifer Garner appeared to be in good spirits as she was busy filming after her ex-husband Ben Affleck tied the knot with Jennifer Lopez over the weekend.

The American actress, 50, kept it casual as she was spotted on the set of her new TV show The Last Thing He Told Me on Tuesday.

She looked effortlessly stylish in olive green jeans and a white V-neck T-shirt, which she teamed with a pair of white trainers.

Jennifer slung a dark jacket over one arm and accessorised her chic ensemble with a silver pendant necklace as she shot scenes.

The 13 Going on 30 star styled her fringed brunette tresses loosely in natural curls and framed her striking features with a square pair of glasses.

She accentuated her natural good looks with lashings of mascara and a light dusting of make-up while she flashed a huge smile during filming for The Last Thing He Told Me.

Based on Laura Dave’s best-selling novel of the same name, Jennifer plays Hannah Hall, a woman forms an unexpected relationship with her stepdaughter as she searches for her husband who recently disappeared.

It comes days after her ex-husband Ben Affleck tied the knot with Jennifer Lopez, who he was engaged to in 2002 before they called off their wedding.

Yes Day actress Garner married Affleck, 49, in 2005 and they share three children together; Violet, 16, Seraphina, 13, and Samuel, 10.

They announced their split after ten years of marriage in 2015 and have remained close in each other’s lives co-parenting their children.

Garner and Affleck’s children, Seraphina, 16, Violet, 13, and Samuel, ten, spent Saturday evening witnessing their father tie the knot with Lopez in Sin City.

They, along with Lopez’s 14-year-old twins Emme and Max, flew to Las Vegas to share the special day with their father and new stepmother. 

Garner kept herself busy over the weekend as she enjoyed a trip to Lake Tahoe, hours away from Los Angeles.

Taking to Instagram, she shared a short video snippet of her feet dangling over the lake. It was soundtracked by the emotional 2019 song Circles by Post Malone.

But it appeared the 13 Going On 30 star was in good spirits as a second post shared to the app’s Stories showed her smiling.

Elsewhere on social media, it was business as usual for Jennifer as she shared a promotional video for her brand Once Upon a Farm.

The entrepreneur created a reel showing her prepare a hearty lunch that included stove-popped popcorn, a toasted sandwich, and a smoothie packet.

The cute and creative content showed her in leggings and a sweatshirt with her hair pulled up as she bustled around the kitchen.

She captioned the snippet: ‘Lunchbox handled. (with @onceuponafarm!).’

On Saturday, Affleck and Lopez tied the knot in a surprise Las Vegas wedding ceremony, with their kids attending the nuptials.

Revealing the news, Lopez wrote in her newsletter: ‘Last night we flew to Vegas, stood in line for a license with four other couples, all making the same journey to the wedding capital of the world. 

‘We barely made it to the little white wedding chapel by midnight. They graciously stayed open late a few minutes, let us take pictures in a pink Cadillac convertible, evidently once used by the king himself (but if we wanted Elvis himself to show, that cost extra and he was in bed).’

Lopez also revealed she wore a dress from an old movie, while Affleck wore a jacket from his closet for the ceremony.

She said: ‘We read our own vows in the little chapel and gave one another the rings we’ll wear for the rest of our lives. In the end it was the best possible wedding we could have imagined.’

The chart-topping star also signed the letter using the name ‘Jennifer Lynn Affleck’.

Their wedding came nearly 20 years after the couple called off their engagement due to ‘excessive media attention’.

At the time, they had hired decoy brides to appear in various locations to dupe the paparazzi.

This time around the pair slipped away with their kids for an intimate ceremony.

‘They both thought it was a fun and casual way to tie the knot,’ an insider revealed about their low-key nuptials.

Despite their Saturday ceremony, the couple are planning on having a big wedding with friends and family in the near future, according to People and TMZ.

But the actors, who rekindled their relationship last year with an engagement in April, do not yet have a honeymoon in mind, it was claimed.

People shared on Monday that the elopement is just the start of the smitten couple’s wedding season.

The newlyweds – now Mr and Mrs Affleck – ‘plan on having a bigger party so they can celebrate with family and friends’, it was reported. People did not name when or where their second wedding will take place.

Lopez’s closest family members are her twins Max and Emme as well as her mother Guadalupe and father David, and sisters Lynda and Leslie. Her best celebrity friends are Leah Remini, Jane Fonda and Renee Zellweger.

Affleck’s family includes his three kids Violet, Seraphina and Samuel. He is also close to his brother Casey and mother Chris. His famous pals include Matt Damon and George Clooney. 

TMZ shared on Monday that the big bash will take place at Affleck’s home in the coastal town of Riceboro, Georgia which is just outside of Savannah.

The two-story mansion has four bedrooms and four-and-a-half bathrooms. There are also two other smaller properties on the grounds with additional bedrooms.

And the site claimed that the event will take place in the next few ‘weeks’.
