Ben Affleck is living his life to the fullest with his new girlfriend Lindsay Shookus following his split from estranged wife Jennifer Garner. The "Justice League" actor was spotted smiling from ear-to-ear during a casual outing with the "Saturday Night Live" producer on Sunday, August 20 in New York City.

The 45-year-old actor dressed down in blue leather jacket and red T-shirt, which had Vibes written on it. He paired it with jeans and blue sneakers. His 37-year-old lady love also opted for a laid-back look in striped tee and black bomber jacket. Lindsay put a leggy display as she was clad in a pair of very short Daisy Dukes and white sneakers.

The two were spotted entering a jewelry store. It seemed like Lindsay had her eye on some jewelry. The Oscar-winning actor could also be seen stopping for a while to happily give his autographs to his fans.

Later on the night, the couple was photographed having a romantic dinner at trendy French-American restaurant Mas (farmhouse) in Manhattan. For the date night, Ben donned the same red tee beneath his blue sport coat. As for the bottoms, the brother of Casey Affleck opted for curduroy pants and sneakers. Meanwhile, Lindsay looked stunning in a black cape top, skinny jeans and nude wedges.

As Ben and Lindsay's relationship continues to heat up, the "Gone Girl" actor reportedly wanted to introduce Lindsay to his family. However, Lindsay was said to be horrified by the idea since she feared that his family would think she wrecked his marriage to Jennifer. "She's terrified at facing their questions on how she and Ben met and fell in love. But she's starting to run out of excuses - and Ben's family members are beginning to wonder what's up," said a source.
