Jennifer Lopez says Ben Affleck was the first guy who broke her heart.

The 'Booty' hitmaker, who got divorced twice before she started dating the 'Gone Girl' actor in 2002, was completely devastated when they ended their engagement in 2004 even though she married her third husband, Marc Anthony, six months later.

In an upcoming interview with Maria Shriver that will air on the 'Today' show on Monday (03.11.14), the 45-year-old beauty admits she moved on from the 'Argo' actor very quickly with one of her ''best friends'' and didn't give herself time to ''heal.''

Discussing their split, she said: ''It was probably my first big heartbreak, and to have one of my best friends who I'd known for years, who I actually love and did have chemistry with, come into my life and say, 'I'm here'...What you need to know is, nobody can save you or heal you. Only you can do that for you.''

The 'True Love' author, who split from Marc in 2011 and dancer Casper Smart earlier this year, is still adjusting to being single.

She said: ''It's still a work in progress for me. It's how you feel as a child, you know, being a middle child and kind of being invisible sometimes, or, you know, trying to get the attention.''

She added: ''I'm open to love, but right now, I think it's better to just be on my own for a minute and learn more about myself.''
