Taylor Swift, Blake Lively, Selena Gomez Complicated Friendship Triangle

Taylor Swift, Blake Lively, and Selena Gomez are allegedly best friends, but the three are rarely all seen together.

Some have assumed the trio's schedules simply do not gel well together since they are all busy with their respective careers -- Swift with her music and tour, Gomez with her cooking show, music and TV series, and Lively with her kids and other events.

Insiders are now disclosing the unexpected reason why they think the three women are never seen together: they just cannot all be together because there will be some unnecessary tiff.

The insiders claim that while Swift is good friends with the other two, they are too different to be in each other's presence, even if they commonly love Taylor Swift.

So, if Taylor Swift wanted to spend time with both of them, she has to do it separately.

According to insiders, she personally wants it that way, too.

When football enthusiast Selena, 31, failed to show up for Taylor's A-list group at this year's Super Bowl, some heavy questions were raised.

Although Selena and Taylor were rarely photographed together, they had already become friends when Blake entered the picture in 2015. The two had initially become friends in 2008.

Desperate Swiftie investigators have been attempting to determine why Selena, a devoted football lover, did not attend the Super Bowl. Rather, Selena only remarked on a picture of the Taylor with her friends from the big game, which included a dejected face emoji and a black heart.

Unlike Blake, who was spotted with Taylor at three games last season, Selena has never gone to support Travis with Taylor.

Moreover, numerous events, including Taylor's birthday celebrations, Fourth of July get-togethers, and New Year's Eve festivities, usually have one or the other there, but not both.

Real Reason Why Taylor Swift Cannot Be With Selena Gomez and Blake Lively Together

Some insiders said that the two are not necessarily feuding. It's just that they each have personalities that do not gel well together, and Taylor Swift views them as perfect for different purposes.

"For a good hangout and good party, you know who to invite and who not to invite," one insider explained to the Daily Mail. "Taylor knows not to mix Blake and Selena in the same room and that it must be two separate nights," the insider added.

The insider said Blake is meant for those events, and Swift just wants to chill and laugh.

"Blake enjoys the perks of being a celebrity. She loves to have fun," the insider said.

"If there is something fun going down, she wants to be a part of it and it is contagious. This is something that everyone, including Taylor, loves about Blake. She knows that, no matter what, she is going to have a good time and lots of laughs when she is out with Blake," the insider added.

Another insider said, "Blake will be in the mix when Taylor wants to hang loose. Selena just plays a different role in Taylor's life. It is as simple as that."

Back in 2016, Gomez said she could be Blake Lively's friend, but they are not. She did not mean they were fighting, though, just that they never met yet.

"I wish she was my friend, but she's not my friend," she said. "Blake Lively. I've never met her, but I just love her hair. I think she's got beautiful, effortless hair. I think she's super beachy."
