The 25-year-old Saturdays' singer tweeted her excitement over her baby boy's big day.
Last night, she wrote: "Can't believe my little monster is 1 tomorrow!! Where has a year gone?! [sic]"
Then this morning she tweeted: "Officially little mans birthday! [sic]"
It seems Frankie's band mate Rochelle Humes is just as surprised at how fast the time is going.
Rochelle posted: "Happy birthday to little Parker @FrankieTheSats cannot believe he's one today. Lai is looking forward to your party. Big kisses for P. [sic]"
Their fellow Saturday Mollie King had a cheekier message, writing: "Happy 1st Birthday little Parker!!! You know you're allowed to be extra naughty of your 1st birthday don't you?!xxx [sic]"
Proud mummy Frankie today retweeted a montage pictures, showing Parker with his aunty Victoria Sandford.
She admitted she's hoping Parker brings her luck as she dances again tonight on Strictly.
"Super super nervous tonight! Let's hope it's an extra good one for little mans birthday! hopefully Parkers my lucky charm… [sic]"
