If you feel you recognise the latest crop of Britain's Got Talent acts then you're probably right.
The ITV series has once again come under fire for featuring a load of 'old' talent, despite Simon Cowell branding a number of acts as the 'future'.
Tonight's episode sees dance group IMD impress the panel however they previously made the final of Got To Dance on Sky1 last year (and in 2013 as well), just like last weekend's dance act - and Ant and Dec's golden buzzer choice - Boyband.
And star of the show hypno-dog has also previously appeared on TV and newspapers, making headline news only last November.
Gospel choir Revelation Avenue Singers appeared on BBC One series Last Choir Standing, alongside another of this year's BGT acts, Welsh choir Ysgol Glanaethwy who we saw audition for the current series earlier on in the month.
Meanwhile singer Isaac Waddington has Simon Cowell declaring in the show this weekend: “We have found someone really special.”
But the teenager won a singing competition on BBC Radio 2 back in 2012 and has also performed BBC One's Songs Of Praise.
A spokesperson for Britain's Got Talent insisted that there were "no rules" stopping such acts from auditioning for the judges.
They told the Daily Star newspaper: “Some acts have previously appeared on other shows.
“But there are no rules that state this should prevent them from applying.”
However it would be nice to perhaps see a truly unique act one day...
