The singer has reportedly said yes to the DJ after taking some time to think about it, the Daily Star has reported.
A friend of the 23-year-old's told the newspaper that the 29-year-old asked Rita to move into his LA home so their work commitments don’t lead to a break-up.

'He believes they can make their relationship last if they both fully commit to it,' they added, after the pair were reported to be on the rocks earlier this year.
'Rita took her time making the decision. But she does spend a lot of time in LA anyway and has friends there. So in the end she knew it was the right thing to do', the source added.
The I Need Your Love star is thought to have been over-the-moon after she agreed to the plan.
She tweeted on Saturday to say: 'Clear out at mine I forgot I had all this fancy dress! I don't wana get rid of anything! 2014…', along with a picture of herself sporting a colourful wig, sunglasses and an over-sized chain necklace.

The star was spotted arriving in to Manhattan's JFK Airport wearing a black and white Fendi fur coat, a rock and roll T-shirt, a yellow Adidas beanie and above-the-knee black boots.
And, whether she planned it or not, the outlandish fashion statement left her looking distinctly like a garden variety bee.
