Jhene Aiko tattoos boyfriend Big Sean's face on her arm

Singer Jhene Aiko has proved her devotion to boyfriend Big Sean by getting the rapper's face tattooed on her body.

The While We're Young singer showed off a portrait of the Control rapper on her arm in a picture posted to Instagram by Los Angeles-based tattoo artist Miryam 'The Witchdoctor' Lumpini.

The tattoo features Sean, who she began dating last year (16), in a tuxedo similar to the one he donned when he and Jhene attended the Elton John AIDS Foundation ball in February.

Jhene and Sean, who has previously been linked to Ariana Grande and was also engaged to former Glee star Naya Rivera, announced their relationship late last year - soon after the singer's split from her producer husband of 11 months, Dot Da Genius.

The couple, who together form duo TWENTY88, last year released an album of the same name before going public with their romance. And in an interview with Flaunt magazine last year, they also talked about their motivation for working together.

"Music now doesn't really cater to the feelings of a real relationship. It's all about trapping and bragging," Jhene sighed. "I feel like this project is something that's needed right now. Especially a whole project is just good for people to see. That duality is a perfect combination. It's a 70's aesthetic, but we're in the future."

Sean recently teased the couple are planning to release more music together, as well as their own solo efforts.
