Idris Elba's fiancée Sabrina Dhowre believes she is ''lucky'' to have found him.

The 29-year-old model got engaged to the 'Luther' actor earlier this month when he popped the question during a packed screening for his new film 'Yardie' in Dalston, east London, and she has now taken to Instagram to gush over her husband-to-be.

Sharing a snap of herself and the Hollywood hunk, 45, enjoying a romantic dinner together, Sabrina wrote: ''Baby! I can't tell you enough how happy you make me and how lucky I feel to have found a love like this, you make my heart feel so full. I love you. Forever will always feel to short. #imsuchacheeseball @idriselba (sic)''

It comes just days after Idris got down on bended knee during the film screening at the Rio Cinema on February 10.

The cinema announced the news on its Twitter page, writing: ''Another @riocinema first! Still 5 days to Valentines Day but @idriselba went down on one knee and proposed to his girlfriend live on stage this morning before a preview of his film #Yardie ... She said yes and there was much clapping and cheering. (sic)''

Previously, the 'Thor: Ragnarok' star - who has been married twice, first to Kim Norgaard, with whom he shares son Isan, and then Sonya Nicole Hamlin, whom he divorced just four months later - insisted he wouldn't get married again after the heartache of his previous two splits.

He said: ''Am I ever gonna get remarried? I don't think so. Yeah, I don't think so. Marriage is an institution of sorts. And I've done it. It's not for everybody. It's not my life's calling.''

His ex-wife Sonya had previously claimed he dumped her for the sake of his career but said she would be happy for him if he did want to get married again.

In 2016, she said: ''People were telling him he was going to ruin his career. He was being told it was an important part of his image to be a single sex symbol in Hollywood and being married would damage that.

''I'd be happy for him if he got married again, and he genuinely loved that person. I'm not a jealous person. I want him to be happy, just like I'm sure he wants me to be happy. I don't think he's ever going to have a problem being lonely.''
