Ariana Grande and Ethan Slater are keen to keep their relationship out of the spotlight

Ariana Grande and Ethan Slater have "always preferred to be low-key".

The 32-year-old star and Ethan, 33, are conscious of the online speculation surrounding the state of their relationship, but they spent some quality time together after attending the London premiere of Wicked: For Good.

A source told The Sun newspaper's Bizarre column: "Ariana and Ethan are still a couple but they’ve seen the chatter online and it’s not been easy.

"They were both at the ­Leicester Square premiere and the ­after-party at Brasserie Zedel but made sure they weren’t seen together."

Ariana and her Wicked co-star are keen to ensure that their romance doesn't play out in public.

The insider continued: "Obviously it fuels the ­speculation around them but they don’t want their relationship to play out in public.

"When Ariana left the after-party, she went back to her hotel suite.

"Not long after, Ethan was taken there and went up to see Ariana to spend time with her.

"They are aware of what is being said and it’s not easy for them but they’re doing the best they can to snatch some quiet moments when no one is watching."
