Okay, maybe they weren't there WITH John Mayer, but he was performing at the concert they were attending and that counts, right?
The adorable duo were spotted looking so cute with Hilary all bundled up with a hat, scarf and sweater while Mike kept it simple with jeans, a black t-shirt and a leather jacket.
We didn't realize you needed to protect your skin from the moon too!
The two were seen holding hands as they entered the Hollywood Bowl for John’s concert.
How AMAZEBALLS would it be if the three of them collaborated for a track on Hilary's new album?!
