Two Hollywood couple breakups surfaced as Taylor Swift and Calvin Harris called their fifteenth month-long relationship off, while Gigi Hadid and Zayn Malik broke up after seven months of dating.

International DJ Calvin Harris whose real name is Adam Richard Wiles, took to Twitter to confirm his breakup with American singer-songwriter Taylor Swift. In his tweet, Harris said that their relationship simply came to an end.

"The only truth here is that a relationship came to an end & what remains is a huge amount of love and respect," Harris wrote in his tweet which Swift retweeted.

"Taylor and Adam had no big blowout fight, but the romance just was not there anymore for them," E! News reported a source as saying. "Adam is the one that ended it."

"It was all done in a very mature fashion," the source added. "Taylor is pretty upset but they are still in communication."

In March, the couple celebrated their first anniversary in a beach.

Meanwhile, Victoria’s Secret Angel Gigi Hadid and former "One Direction" member Zayn Malik also called their relationship off after dating for nearly seven months.

The reason for the split up remains unknown but some "rough patches" within the relationship has reportedly been there for quite a time.

"During her birthday they were fighting," E! News reported an insider as saying. "They weren't doing well then, and has broken up and got back together a few times."

The source adds that there have been some communication issues with the couple lately. They also haven’t been getting along as well as they used to.

"Gigi is really sad about this, though, and in a way would like to work it out," the source said. "It's more about that constant contact with Zayn that she misses and they did get very close."
