They were barely over and now they're back together but it's not exactly smooth sailing between the pair.

According to Us Weekly, Gigi Hadid and Zayn Malik are back on after splitting up last week but things are tense and it could all be over any second.

"They broke up and got back together almost right away," a 'pal' told the magazine. "Right now it’s back on, but it could be off again in an hour. They are young and keep going back and forth. Things are testy between them."

Zayn's track record for romance isn't exactly A1, but we have a feeling Gigi is plenty ready for him.

A second 'insider' told Us Weekly that personality clashes are also at the root of their rocky relationship. "He wants to stay home and hang out, but she loves the limelight. She loves attention and he hates it. An introvert and an extrovert; we all saw it coming."

So don't hold your breath for this to be everlasting then.
