Jennifer Lopez is very supportive of her boyfriend Ben Affleck's career and is constantly encouraging him and showering him with praises and kind words to help him be the absolutely best version of himself.

"Ben and Jen have both been busy working. Ben is just happy with life right now and it's been a while since his friends have seen him in such positive spirits. Jen helps bring out his best self,” a source tells ET Online

"His career is going well, and he has so many projects lined up. He is really proud of 'The Last Duel' and happy that Matt and him got to do it together. Jen is so supportive and is always pumping him up and saying how talented he is. He has been working out as well and feels great," the source shared.

"He has always been funny, creative, smart and caring, but the difference lately is he is always smiling and happy. You can tell he just is so positive and appreciative of how great things are going right now."

The source then spoke about how Affleck is grateful to have Lopez in his life. “It took him ups and downs to get to this place. He loves Jennifer and says she makes him a better person and motivates him to work hard. He wants to take care of her, even though she doesn't need him to. That is just the type of guy he is." 

Affleck, 49, and Lopez, 52, first connected in 2002, while working on a movie together. 

The "Argo" star proposed to the "I'm Real" singer in November 2002. They were set to get married in 2003, but their wedding was called off just days before  the ceremony due to “excessive media attention,” states Us Weekly

In 2004, the couple officially announced they were going their separate ways. However, after 17 years apart, Affleck and Lopez confirmed that they were back together in May 2021.
