Jonas Brothers headline this year's BLI Summer Jam at Jones Beach

Get ready for the return of “Jonas Beach.”

Yes, the reunited Jonas Brothers will top the pop-star traffic jam at Northwell Health at Jones Beach Theater this weekend, as both WBLI/106.1 FM and WKTU/103.5 FM host their annual summer-kickoff radio shows.

Both lineups are stacked with hitmakers. But the JoBros, who broke up in 2013, come into the weekend with the most buzz. They landed their first No. 1 single ever with “Sucker” and they expect to notch another No. 1 album with “Happiness Begins,” released last week. “This could have gone terribly wrong,” Nick Jonas recently told Harper’s Bazaar. “We’re grateful the pieces came together.”

Because their tour doesn’t kick off until August, the Jonas Brothers’ appearance at BLI Summer Jam is much anticipated, especially since the band has always had a strong Long Island following. In 2010, they played two shows at Jones Beach, and taking a cue from eager fans, the venue changed much of its signage to “Jonas Beach” during the run.

Of course, Nick, Joe and Kevin aren’t the only stars set for Wantagh this weekend. Here’s a look at some of the others:
