As the star spends more time in the Hamptons, celebrating her birthday apart from Ben Affleck, a source tells PEOPLE, "Her summer isn't exactly what she originally had planned, but she's making the best of it. She's always grateful for family time." Over the weekend, Lopez, who turns 55 on Wednesday, July 24, hosted a Bridgerton-themed birthday party, followed by an intimate birthday lunch with close friends and family the next day. "She had a great weekend with family and friends," says the source. "She loves entertaining and enjoyed her birthday bash. She was in a happy mood." Lopez's summer was originally mapped out to look a lot different. For one, the star, who launched the Netflix movie Atlas to No. 1 on the streaming service in May, was scheduled to go on a This Is Me... Live concert tour, which would've taken her to Austin, Dallas, Las Vegas, Miami, Toronto, New York City, Boston and more.
