One is a member of the sexiest boy band around.
The other has suffered a devastating personal tragedy.
But both turn a year older today, as Liam Payne is now 20 years old and Lea Michele is 27.
Payne is riding high these days, with One Direction winning an MTV Video Music Award Sunday night and with his group's new movie coming out tomorrow.
He does think Taylor Swift is sort of lame for continually bashing bandmate Harry Styles, but can you blame the cute for being loyal to a friend?
Michele, unfortunately is as low as it gets right now, still struggling with the death of boyfriend Cory Monteith.
She moved Teen Choice Awards viewers to tears with an emotional acceptance speech this much and she's back on the Glee set now, filming Season 5 of the hit Fox series.
Join us now in wishing both these impressive singers nothing but the very best on their special days. Good luck with those birthday wishes, Liam and Lea!
