Olivia Rodrigo has become the first female artist to have three solo songs on a single album reach a billion streams on Spotify.

The 19-year-old pop megastar has made history after her third hit single from Sour, "deja vu", exceeded the 1 billion mark on the streaming platform, according to a tweet by Chart Data. "drivers license" and "good 4 u" also crossed the milestone.

Meanwhile, the Grammy winner has been back in the studio working on her second album. Olivia's producer Dan Nigro shared a studio snap of the pair on his Instagram Story in August, confirming a previous report that they are hard at work on the follow-up to Sour. After the whirlwind success of her record-breaking debut LP, the singer-songwriter reunited with the studio wizard behind all but one of the 11 tracks on the chart-topping 2021 record.

Meanwhile, the former Disney Channel star recently insisted that she won't be getting her head turned by her success. She said: "I definitely think it is a big confidence boost to see so many people resonate with what I have to say. I'm so grateful for that.

"I'm just always a little bit hard on myself. I'm always pushing myself to be better.

"And I think I'll never change no matter the amount of success any of my songs get."

Rodrigo admitted that the last year has been "crazy" and though everything around her has changed, she's still the same person and her friends will always keep her grounded.

She said: "It's so crazy, but I have amazing friends who are so honest with me and keep me grounded.

"My life has changed drastically, but at the end of the day, I'm really kind of like the same person doing the same things in my everyday life."
