Jennifer Garner is not bitter at all over ex-husband Ben Affleck’s new romance.

On Saturday, the “Alias” alum was spotted with a big smile on her face while leaving a fitness class in West Hollywood, California. It was the first time she was seen after Affleck’s new girlfriend was revealed, Entertainment Tonight reported. Garner, 45, did not show any hint of sadness over the reports that her ex has found love again just months after they officially filed for divorce.

 In the photos shared by Daily Mail, Garner wore an all black ensemble for her class, including a short-sleeve top and pedal pusher leggings. She paired her workout ensemble with blue Asics running shoes. The “Miracles from Heaven” star was seen holding a bottle of water in her hand when she left the venue.

Earlier reports claimed that Garner was not happy with Affleck’s relationship with Lindsay Shookus, who was one of the women linked to him in the past. “It’s not an easy situation for Jen,” one source told People of Garner after the dating news broke.

However, the mother-of-three was apparently already aware that the “Justice League” star would start dating after their split and divorce filing because Affleck is not the type who enjoys solitude. “She knew it would happen soon. Ben just can’t be alone,” the source added.

Affleck and Shookus allegedly had an affair in 2013 while the “Batman” star was still with Garner. However, it was only in 2015 when the “13 Going on 30” star learned about their fling. Other sources close to the pair insisted that they were just friends, that is until they separated from their respective spouses and decided to publicize their romance. Shookus and her husband, Kevin Miller separated in 2014. Meanwhile, Garner and Affleck split in June 2015, a day before their 10th wedding anniversary.

One source believed that it would have been easier for Garner if her estranged husband started dating someone new, like a woman who is not familiar with her. Meanwhile, another insider didn’t think Affleck and Shookus’ relationship matters anymore. “Of course there are issues given it was a major affair, but Jen is her own woman and is completely fine. Nothing is new for her here. She’s in mama-bear mode . . . putting the kids’ happiness first,” the source said.

As of now, Affleck and Shookus are reportedly trying to keep a low profile with their budding romance. However, they were spotted watching Sam Mende’s play “Freeman” together in a trip abroad a few weeks back. They were also seen going out last Thursday for a quick date night.
