Looks like Liam Payne doesn't believe in birthdays so much as birthweeks.
Though it's today that he turns 19, the One Direction member wasted no time getting the celebrations started, kicking off the festivities Saturday at London club Funky Buddha with a surprise party thrown by his dancer girlfriend, Danielle Peazer, and his bandmates.
The "What Makes You Beautiful" singer tweeted a pic of himself from the event with an elaborate Batman cake, and let loose later in the evening by enthusiastically spraying his friends and loved ones with champagne.
Sounds like a good and rowdy time was had by all, as on Monday Liam tweeted, "Had a few really busy but brilliant dayss .... 2 days to my birthdayyy wooowwww weeee :)"
And the celebrations continued today, when his bandmate Niall Horan tweeted out birthday wishes to the singer.
"Happy birthday to @Real_Liam_Payne, the big fella is 19!" he wrote. "#upthelads! Love ya bro"
Happy birthday, Liam! No telling what the young star and his pals have planned for the big day today, but we're sure it'll keep them up all night.
