These two were on the Jimmy Fallon show last night to chat about their new rom-com 'Blended' which is out shortly. As we all know though, these two are no strangers to each other when it comes to the old romantic comedies, having starred in The Wedding Singer together in 1998, and then 50 First Dates in 2004.

Ten years later, they are back falling in love all over again, which led Jimmy to ask if they'd 'like to express those feelings in song', as he pulls out his trustee guitar. So, the pair took to the stage and performed the 'Every Ten Years' song, with the highlight really being when Adam slipped into the famous Wedding Singer song, 'I Wanna Grow Old With You'.

You can take a look below, and no we don't know why Adam looks like he just rolled out of bed, but we can tell you that heavily pregnant revealed to Jimmy that she was having another daughter. Naww.

And while we are here, how could we not?
