"Sometimes life just happens... For whatever reason in whatever timing. And sometimes it doesn't make sense till it does. That's it," the 20-year-old Victoria's Secret model posted and then deleted it.
After deleting the text, she later posted a scenic beach photo with the words "Chill".
The tweets come after fans have questioned Hadid's dating habits following her early November split from Jonas.
Shortly after calling it quits with the DNCE band leader, Hadid went public with new boyfriend Zayn Malik, days after sources confirmed they were an item.
