It's a sad day for young love when one of the most Instagrammable couples in the world, Gigi Hadid and Zayn Malik, announce their split after two years

The 25-year-old ex-One Direction singer and 22-year-old model have called time on their relationship after two years with both parties taking to Twitter to formally "announce" they're now single, but probably not yet ready to mingle.

Both Hadid and Malik tweeted nice, kind words about the other party, hinting that the split isn't in any way bitter but rather due to conflicting work schedules, with a source telling The Sun, "They have crazy work schedules that would put pressure on any relationship."
