The Daily Heat Index: Here’s the Reason Why Selena Gomez is Going on a Career Hiatus

Plus: Karen Gillan joins The Rock in ‘Jumanji,’ and Nick Offerman teaches us the history of exercise.

Here’s a daily dose of what’s heating up the internet:

Selena Takes Time Off
A year after publicly announcing her Lupus diagnosis to the world, “Hands to Myself” singer Selena Gomez has decided to take some much needed time off to deal with the disorder’s side effects, like “anxiety, panic attacks and depression.” The 24-year old, who recently finished up her massive Revival tour and made an on-screen appearance in Neighbors 2, told People that she needs “to face this head on to ensure I am doing everything possible to be my best.” We wish all the best to the world’s reigning Queen of Instagram as she recovers.

The Rock Welcomes Karen Gillan
The upcoming Jumanji film (labeled as a continuation, not a reboot), has been in hot pursuit of a female star to join Dwayne Johnson, Kevin Hart, and Jack Black, and it looks like they found just that in the form of ravishing redhead and former star of the nerd-tastic Doctor Who sci-fi series, Karen Gillan. As an avid social media user, Johnson took it upon himself to announce Gillan’s casting on Instagram, praising her talent and “chutzpah” with an accompanying sexy shot.

Nick Offerman Gets Physical
A mustache-free Ron Swanson (Nick Offerman) zooms through the greatest fitness trends of the past 75 years for Funny or Die’s latest video to promote FLOTUS Michelle Obama’s #0to60 campaign. There’s no Lagavulin featured, but there is plenty of spandex, shake weights, and a solid Megan Mullally cameo.
