The two teenage singer-songwriters will go head to head on tonight's final.
Up for grabs is a whopping £500,000 cash prize and a Royal Variety performance, and the very similar acts are sure to split opinions.
Speaking ahead of this evening's final, Alesha said today: "I love Ryan. He’s got a similar style to Sam. They both gave such stripped down performances without any razzle-dazzle.
"They’re both so humble and modest; neither of them can believe they’ve made it this far."
She added: "I’d like to see those two collaborate together in a studio. You can see backstage how brilliantly they get on – I think they’ll be friends for life."
Tune in to Britain's Got Talent 2012 tonight to see which - if either - triumphs in the final!
