Hailee Steinfeld pushed Sophie Turner to date Joe Jonas.

The 21-year-old singer-and-actress is ''freaking out'' about the couple's recent engagement and admitted she encouraged the 'Game of Thrones' star to go out with the DNCE hunk after Sophie turned to her for advice.

Speaking to Nova's Smallzy on Wednesday (31.01.18), Hailee said: ''So Joe just got engaged to my really good friend Sophie Turner and I'm freaking out about it.

''I will say I did get that text from Sophie saying 'So tell me about Joe?' and I was like 'Go for it!'''

The couple haven't started planning their upcoming wedding, but another of Sophie's close friends, her 'Game of Thrones' co-star Maisie Williams revealed she is going to be her bridesmaid.

When asked if she was hoping to be secure a bridesmaid position for the nuptials, Maisie said: ''Oh, already got it. Yeah, it's very, very exciting. It's kind of bizarre though.''

Maisie also revealed that Sophie is keen to wrap filming on the final season of the hit HBO show - which will air in 2019 - before she lets wedding planning take over her life.

She said recently: ''We're waiting 'til this season's done until we get into it. But I think she's already letting her little heart wander and imagine.''

Meanwhile, former Jonas Brothers star Joe still has to decide who to appoint as his best man, with the options likely being between his brothers and former band mates Kevin and Nick Jonas.

Nick previously insisted he would be honoured to take on the role, but pointed out Kevin's 2009 marriage to his wife Danielle saw both himself and Joe act as dual best men.
