You actually won't believe who 50 Cent's celebrity crush is!

After they posed together for a series of very flirty red carpet photos last week, it seems Helen Mirren has left a lasting impression on the 'In Da Club' rapper.

Taking to his Instagram account, 50 Cent informed his 15 million followers: he's hot for Mirren. 

The 41-year-old rapper posted a photo of one magazine article and wrote: 'I think I love her man, I'm trying not to stare at her.'

'She know she turns me on. She just has that thing (sic), you know I can't describe it. LOL,' he continued of the British actress, 71, who is married to American director Taylor Hackford.

We can't blame him though, she is irresistible!
