The loved-up duo, who began dating earlier this year (21), looked smitten as ever as they attended the MTV Europe Music Awards (EMAs) in Budapest at the weekend (14Nov), and it's now been claimed the "I Will Never Let You Down" singer has since introduced the director to her parents in London, according to Britain's The Sun newspaper.
The "Fifty Shades Freed" actress recently admitted she is in a "great place" with her beau, but the singer - who previously dated the likes of Calvin Harris, Ricky Hil, and Rob Kardashian - is reluctant to talk about their relationship because she's learned from her mistakes.
Confirming things are going well between them, she said, "I'm in a great place in my life, that's all I'm going to say about that."
"I just think, respectfully, privacy is important. Yeah... I learned a lot in my 20s."
It was reported in the summer that Rita - who bought a new house in London last year (20) - was moving to Los Angeles to live with the "Jojo Rabbit" filmmaker.
The "Hot Right Now" singer and Taika were first spotted together in Australia in April but it's believed they started dating in March.
While they have made red carpet debut as a couple at "The Suicide Squad" premiere, the singer was still reluctant to talk about her romance in interview.
"I'm in a great place in my life, that's all I'm going to say about that," she recently said when asked about her boyfriend.
