Olivia Rodrigo and Zack Bia have called it quits after a few months of dating.

The 19-year-old Grammy winner and Bia reportedly broke up due to conflicting schedules.

"Their relationship sort of fizzled. They were casually dating but haven't spent time together in a while," a source told Life & Style exclusively.

Despite their split, the source emphasized that "there were no issues [between them], they both have different work schedules and different friend groups."

Speculations about the ex-couple's relationship began in April when they were spotted walking around New York City with Bia's arm draped over the "Deja Vu" singer's shoulders.

Rodrigo was previously linked to Adam Faze before they broke up in February after dating for less than a year. Before Faze, Rodrigo was also linked to her "High School Musical: The Musical: The Series" co-star Joshua Bassett. At the time, there were rumors that Rodrigo's debut album "Sour" was about Bassett. Neither of the two stars had confirmed or denied their romance. But fans were convinced Rodrigo was singing about Bassett and his rumored girlfriend, Sabrina Carpenter, in the track "Driver's License" because of the lines "that blonde girl" and "she's so much older than me."

Rodrigo earlier told GQ that she avoids reading what people have to say about her love life.

"I try not to look at stuff like that, to be completely honest. I like to think that if there's actually something that I should know about, my team would tell me," she said. "It was really hard for me to watch people on TikTok and stuff that dissects my 17-year-old love life. That was really weird. But again, I think I understood the curiosity. It doesn't affect me; it doesn't matter. It doesn't affect my songwriting and my life."

"It helps to not look at that sh**(social media)," she added.

Bia was previously linked to Madison Beer before he dated the "Driver's License" artist.

Rodrigo also earlier opened up to Vogue regarding the lessons she "learned" from previous breakups.

"Besides cutting off all contact, I think it's important to not only forgive them but forgive yourself for letting everything happen," the "Traitor" singer told the outlet at the time.
