They were either rumored to planning a wedding or splitting, and Taylor Swift and boyfriend Calvin Harris proved that they are above gossip as they celebrated the "Bad Blood" singer's Christmas-themed birthday over the weekend.

The birthday bash was reportedly held in the posh Malibu home of Apple exec Jimmy Iovine.

"Taylor Swift kicked off her 26th birthday with a Christmas-themed bash, complete with a VIP appearance by Santa and Mrs. Claus. Mama Andrea Swift, boyfriend Calvin Harris and DJ Snake were some of the A-list names on the guest list who stepped out on Sunday in honor of the "Bad Blood" singer," E! News said.

The celebration came on the heels of the rumors that Taylor Swift and Calvin Harris are already planning their wedding.

According to an alleged source of In Touch Weekly, "Taylor plans to marry Calvin next year in two different locations - one in the U.K. that will be a huge, over-the-top blowout party and one in either Nashville or LA that will be a little more subdued."

Although she has a long list of designers that Taylor Swift has worked with in the past, Calvin Harris' girlfriend has allegedly chosen Vera Wang to design her wedding gown.

"You can't expect a girl like Taylor to wear the same dress twice! Taylor says that's the best part, aside from marrying the man she loves," the insider adds.

Meanwhile, UK's Mirror claimed that Calvin Harris is already looking for a wedding ring for Taylor Swift and the DJ is preparing to shell out big bucks to purchase the bling.

"He said he wanted something 'very special' for Taylor," the source claimed. "He was asking about the best cuts and eyed a ring that was $1.4 million! He was clearly eager to get the perfect rock, no matter the cost."

Taylor Swift and Calvin Harris just started dating this past summer when they were set up by Ellie Goulding who thought they would be perfect for each other because of their height.
