A timeline of Pete Davidson's romantic escapades, from Ariana Grande to Kate Beckinsale

Pete Davidson might be one of New York City's biggest serial daters.

The "Saturday Night Live" star, 25, made headlines in 2018 for his brief, but highly public engagement to pop singing sensation, Ariana Grande, 25, within just a few weeks of dating.

But the couple split after a short five months, leading Grande to create her smashing breakup album, "thank u, next," and Davidson to move on rather quickly with another celebrity, 45-year-old English actress Kate Beckinsale.
