It looks like Jennifer Garner is ready to move on following her split from Ben Affleck. The "Alias" alum was spotted getting cozy to a mystery man in Los Angeles on Sunday morning, February 11.

In some photos obtained by Daily Mail, the 45-year-old actress was snapped running errands in the Brentwood area. She looked pretty casual in white top and black velvet shoulder back with chain details. She also had a pair of shades which she tucked in her head.

Walking beside her was this mystery man, who casually put his arm around the actress' shoulders. The mother of three also put her arm around the man while one of her hands was holding a cup of a drink. Both looked happy as they were seen sporting big smiles on their faces.

It arrived after Jennifer, who shares three children, Violet, Seraphina and Samuel, with Ben, was rumored to be dating Josh Duhamel. Her co-star in "Love, Simon", who also had gone through a devastating divorce from Stacy Ferguson a.k.a. Fergie, was said to build their romance with Jennifer during breaks from the filming of the coming-of-age movie. "That's the best time for those intimate conversations, the ones you have at the beginning of a relationship to happen," a source previously revealed. "Away from home and looking for companionship, it's easy to see what happened."

While "Josh is trully a good guy, and spending time with him opened her up emotionally," Jennifer allegedly was "still playing her cards close to the vest." However, "she's excited about where this could go."

Jen might be a good partner for the "Transformers: The Last Knight" actor, according to the source. "With Jen, he'd get that in spades. She's very sweet and family-oriented," the source further said.
