Cover girl

Nick Cannon's divorce from Mariah Carey gives him free license to stare a little longer when he hosts the "Sports Illustrated Swimsuit 2016 Revealed Special," an event that has graduated from an announcement on late-night talk shows to its own hourlong platform. Leading up to the drama will be an award to Elle Macpherson and a performance from Like Mike. 9:30 p.m. Saturday, TNT

London calling

TV concerts usually don't make much of a splash, but some artists defy the rules. "Adele: Live in London" features one of those exceptions in an event that could serve as a substitute for actually shelling out a month's rent to see her July concerts in St. Paul. It's more likely that the televised set will only whet your appetite, triggering an appointment with your loan officer. 9 p.m. Sunday, BBC America

Where was I?

Yes, "Last Week Tonight With John Oliver" will mention the presidential campaigns in its long-awaited return, but don't expect TV's most savage — and savvy — commentator to dwell on the circus. What makes this show so special is Oliver's willingness to tackle topics ignored by other comics, not to mention the nightly news. 10 p.m. Sunday, HBO
