VIDEO : Hilary Duff and Matthew Koma Break Up After Only a Few Months of Dating

The two were first linked in January, and displayed plenty of PDA in the following months, including on Duff's Instagram. Duff, who has yet to delete her sexy Instagram pics with Koma, last posted a photo with the music producer in late February. "Take me back to Costa with him," she captioned a steamy throwback shot from the pair's Costa Rican vacation.
