Katy Perry and President Obama tag-teamed a message Sunday night during MTV's Video Music Awards.
Open enrollment for health care exchanges begins Oct. 1, thanks to the Affordable Care Act, and Perry retweeted Obama's note that "If you're one of millions of young Americans w/out health insurance, you can get affordable coverage starting Oct. 1."

Katy Perry performed "Roar" for the first time, and it was glorious.
With a silly voice.

VMAs: Stop all this "what's up Brooklyn!!!" What's up is I'm 10 blocks away in my nightgown trying to keep my dog from drinking his own piss— Lena Dunham (@lenadunham) 4 years ago
More on Drake's MTV VMA performance.
Drake shifts into "Started From The Bottom," obviously.
Because when he isn't taking photos with Taylor Swift, he's a great rapper.
He thanks God, his publicist and his "Mahomies."
Mackelmore & Ryan Lewis, great song, best stage design of the night. Jennifer Hudson so good— Joseph Gordon-Levitt (@hitRECordJoe) 4 years ago
After having a major year with the breakout success of their hit single "Thrift Shop" and the follow-up "Can't Hold Us," Macklemore and Ryan Lewis hit the stage at MTV's Video Music Awards to perform their song "Same Love."

We can't even hear One Direction over the boos! #VMA— Chris Weingarten (@1000TimesYes) 4 years ago
One Direction for "Best Song Ever," which was clearly not the best song of the summer, but #mtv.
