Tall Ships Chicago
10 a.m.-9 p.m. at Navy Pier; $9-$20
A boarding ticket gets you on the pirate-like ships, with programs and activities for the kids. Or just hang out on the pier and watch the big ships come in all weekend (show runs until Sunday).
7:30 p.m. at United Center; $20-$500
Look for the R&B sensation to perform a bunch from her upcoming, yet-untitled dance album, including the first single “Only Girl.” Don’t have tickets to the show? You can catch her after party at Vision Nightclub, starting at 10 p.m. ($20).
