at swimming lessons. Lopez dressed casually in high-waisted jeans, an open tan button-up, and sunglasses. Affleck complemented her earthy warm tones in a gray T-shirt, red plaid button-up, and dark jeans.

The two's grand PDA sighting comes just days after Entertainment Tonightreported that Affleck and Lopez are moving toward getting engaged again. Lopez and Affleck originally got engaged in November 2002. They ultimately postponed their wedding in September 2003, a day before the ceremony was supposed to happen. They broke up in January 2004 before rekindling their romance last spring.

“Ben and Jen can't wait to spend the rest of their lives together and know that they were destined to be together,” the source said. “An engagement is on the table and it has been an ongoing conversation.”

“They actively talk about what didn't work in the past and use those experiences to strengthen their relationship now, for the future and for the sake of themselves and their families,” the source added. “They are committed to having a healthy, everlasting relationship.”

The source also spoke about Affleck's major admiration for Lopez and her career. Affleck was filmed lovingly watching her give her Icon Award acceptance speech at the iHeartRadio Music Awards this week.

“Ben is Jen’s number one fan and he completely champions her and always tells her how great she is. He loves talking about her different projects,” the source said. “She is a huge supporter of his too, but Ben really can't stop telling everyone how smart and hardworking she is.”
