Trying to keep up with Katy Perry and John Mayer's relationship status is a full-time job. Trust us, we'd know.
The on-again, off-again duo seem to be back, well, on yet again after displaying some PDA during their pal Allison Williams' wedding over the weekend. Although neither of the stars have otherwise hinted that they're rekindling their romance, a source tells E! News they're currently back together.
The pair first sparked speculation that they'd decided to give it another go when they were photographed cuddling with each other while seated with guests during the ceremony.
Perry and Mayer's last breakup occurred in mid-July, when E! News learned from a source that they opted to call it quits, again. The insider didn't offer any specifics as to the reason behind the two celebs' decision to break up at the time, but noted that they're known to make up time and time again.
And that's clearly been proven.
Meanwhile, Williams married longtime boyfriend Ricky Van Veen in a ranch wedding Saturday afternoon, her rep confirmed to E! News. The beautiful bride walked down the aisle wearing a handmade couture gown by Oscar de la Renta.
Along with the reunited couple, celebs Bruce Springsteen, Andy Cohen, Tom Hanks and wife Rita Wilson and Lena Dunham were in attendance. E! News can confirm Mindy Kaling and Girls co-star Jemima Kirke also attended.
Williams' rep confirmed her engagement to Van Veen, the 34-year-old co-founder of CollegeHumor, in February 2014.
