Jennifer Lopez is celebrating turning 50 with her biggest tour ever, and all this week we've got your invitation to see it at Wells Fargo Center in Philly.

JLo's It's My Party Tour hits Wells Fargo Center on Saturday, July 20th. Just listen for us to play a song by Jennifer Lopez between 9-5 every weekday through July 12th. If you get through as the correct caller we'll give you a pair of tickets!

But, if you have the SoJO app on your phone, you'll get alerts on what JLo songs we're playing and WHEN. So if you want that inside info to help you win, download our app for free in your app store!
