Tales of Taylor Swift and Calvin Harris romance are all over the web. But latest reports suggest that the "Bad Blood" singer's friends are worried about her DJ boyfriend showing more interest in her bestie Gigi Hadid.

Swift and Harris are two of the most popular and busy artistes in the industry. Recently, the pair made it to the list of Forbes' Highest-Paid Celebrity Couples as well. But Tay and Cal ensure that their busy schedules don't get in the way of their personal life.

The couple has been stealing time off their work to go on dates, party together, catch up with friends and even meet each other's parents. In fact, the latest pictures on Swift's Instagram account reveal that the duo had an amazing time together at their early Fourth of July celebrations.

The "Shake it Off" singer has posted picture of taking a piggy ride on Calvin's back, while her DJ boyfriend uploaded a photo of Tay cooking an awesome BBQ meal for him.

Though everything looks rosy here, Taylor Swift's friends are concerned about Calvin Harris showing sudden interest in Swift's bestie Gigi Hadid.

According to OK Magazine, the "Blankspace" singer's friends have alerted the singer about the DJ's flirty behaviour.

"Calvin has shown a sudden interest in Gigi. And Taylor's friends started to notice that he was pursuing a friendship with her. They don't trust him, but they're trying to support Taylor because they know how much she's in love with him. They think he's not as serious about Taylor as she is with him," a source said.

Apparently, Taylor too has confronted Calvin about the same, to which he said his interactions with Gigi are strictly professional.

"Calvin has been liking Gigi's pictures and her selfies on Instagram the minute they're posted. Taylor confronted him and his excuse was that he was texting and liking her photos because he offered her a major role in his music video. But Taylor's friends aren't buying it," the source said.

The report further speculates that this could well be the reason why Taylor invited Gigi along with her rumoured boyfriend Joe Jonas on a double date.

Little known fact: Karlie is secretly an unofficial historian/London tour guide. Kind of.
