What break-up? It’s back on for Katy Perry and her high-profile ex

They may only have broken up back in March, but it looks like things are already back on track for Katy Perry and John Mayer.

The pair were spotted looking every bit the happy couple on Saturday night as they cuddled and laughed their way through a Fourth of July gig by legendary rockers The Grateful Dead, according to TMZ. Fans were quick to post pictures of the pair on social media, like this one that popped up on Twitter:

Other fans reported seeing the pair enjoying themselves at the concert:

Although Katy didn't reference her cosy evening with John on her own social media profiles, she did subtly allude to her date night by posting this colourful picture of her hand holding a bunch of roses with the caption, "grateful."

This is the third time that Katy and John have reconnected after a break-up. Earlier this year they split following a brief reunion, and sources say the main reason for the split was Katy's busy touring schedule. "John can’t handle the lack of attention, and she can’t handle the trust issues she has when she’s so far away," an insider told RadarOnline at the time.

It was also rumoured that Katy suspected John may have cheated on her while she was away and he was in Los Angeles, though this was never officially confirmed.

Now that the pop star's schedule has calmed down, it seems the pair are trying to rekindle their romance.
