Katy Perry and John Mayer Are Back-On

Katy Perry and John Mayer are back-on!

The on-off couple held hands and cuddled-up to one another at Girls star Allison Williams wedding this weekend.

And although they arrived separately they were inseparable when they got inside the lavish Wyoming ceremony.

The only time the lovebirds separated themselves from each other was to serenade the bride and her new groom, as they individually performed.

Katy wore a long petal patterned gown, while John looked stylish in a black suit, shirt and tie. 

A source at the wedding told People.com that they were 'definitely together'. 

'"John and Katy looked happy. They held hands and sat next to each other during the wedding ceremony," they said.

The couple sensationally split up twice earlier this year -- first calling it quits in March 2015 after a brief reunion in January.

They appeared to reunite again in July and were then spotted together at A Grateful Dead concert, before once again parting ways later that month.

But it seems their latest split was a short-one as they were seen spending time together again in August. 

And now as Allison Williams got hitched to Ricky Van Veen - the pair seem to be closer than ever.

Do you think Katy Perry and John Mayer will last?
