"She was married and had a baby and left her husband to be with Ben," the outlet's source revealed. Lindsay had married her now ex-husband Kevin Miller back in 2010, and the two share one child together.
The source added that Lindsay was often traveling to Los Angeles during her marriage to look for potential "Saturday Night Live" talent and spend time with her new beau. While another insider told US Weekly that the relationship has been going on for three years, adding, "They were not casually dating — they were having a full-blown affair. They were sleeping together, sending each other cute texts and meeting up whenever they could."
During this same time frame, Ben was married to Jennifer Garner. The famous couple announced their split in June 2015, the same year that sources say Jennifer and Lindsay's husband learned about the affair.
Ben and Jennifer officially filed for divorce in April 2017, and it seems Ben is now ready to go public with Lindsay. The two have been spotted out together in London and Los Angeles this summer.
Other sources close to Ben claim the two haven't been dating for years, but rather started seeing each other three months ago, noting, "Ben is enjoying Lindsay's company, and they will continue to see each other."
