Los Angeles, California - Have the stars aligned once again? Fans are in a frenzy as rumors swirl that Harry Styles and Kendall Jenner have rekindled their on-again-off-again romance!

The speculation began when the 27-year-old model attended Styles' concert at The Forum in Los Angeles on November 14.

During his performance of Love of My Life, the 28-year-old appeared to blow a kiss towards where Jenner was standing.

The song he was singing at the couldn't have been more loaded, as it features the romantic lyrics "Baby, you were the love of my life" and "It's not what I wanted / to leave you behind."

Of course, this outing may have just been a pair of friendly exes showing support for one another, but further developments have made this interaction even more noteworthy.

Less than a week after Jenner was spotted at the concert, news broke that Styles and his girlfriend Olivia Wilde had broken up. Just four days later, Jenner's split from athlete Devin Booker was confirmed.

Could these former lovebirds be giving their romance a second chance?

Styles and Jenner were first romantically linked in 2014. Their fling was brief, but they got back together in 2015 and dated for about a year before ending things once again.

The Watermelon Sugar singer was famously coupled up with actor and director Olivia Wilde for the past two years.

Their relationship was a near-constant topic of gossip, from Wilde's custody dispute with her ex Jason Sudeikis to the alleged feuds behind the scenes of Don't Worry Darling.

Jenner, on the other hand, has been in an on-again-off-again relationship with 26-year-old basketball star Devin Booker. Their most recent break-up comes after a brief reunion following another split this summer.

The timing seems a bit too coincidental for many fans of the pair, leading to significant speculation that the former flames may be giving it one last go.
