A rep for Samberg confirmed the happy news to UsWeekly.
The 34-year-old funnyman met the 31-year-old musician through mutual friends. "He liked her music and would go to her shows," a pal told Us last year. "He had the biggest crush on her… they have great chemistry.”
The two have been quietly dating for five years.
