Jaime King tweeted a sweet collage of Taylor Swift and her son Leo on his first birthday.

The 37-year-old model celebrated the little tot reaching 12 months old on Saturday (16.07.16) with an adorable tribute to her best pal.

Jamie - who is married to Kyle Newman - described her only child as her ''miracle'' baby, writing: ''HAPPY BIRTHDAY MY BEAUTIFUL BABY LEO THAMES! I can't believe you are one today. My my miracle.... (sic)''

And alongside a montage of pictures with the 26-year-old 'Shake It Off' singer, she added: ''Wow! @taylorswift13 LT's 1st bday already?! He sends kisses & a bangin' 2 teeth smile to his Godmother in Oz. We (heart) u! (sic)''

Taylor couldn't attend Leo's celebrations because she accompanied her new boyfriend Tom Hiddleston to Australia whilst he films his next movie 'Thor: Ragnarok'.

But the blonde beauty admitted becoming a godmother made her think ''differently'' about life and wrote her track 'Never Grow Up' about the little boy.

She told fans at a concert: ''I wrote it when I was like 18 or 19 but my friend just had a baby and she made me godmother of it and I was holding this little baby the other night and I was just thinking differently. When you're holding onto something that's so innocent and so perfect and has no idea what's coming for it with the world. The world is going to throw so many things at you as we grow up.''

Meanwhile, Taylor was a natural choice to be Leo's godmother.Jamie previously gushed: ''I always thought if I were to have another child that she would be the ideal godmother because the way she not only treats me but the way she treats other human beings. She's so loving and so giving and so generous and she does everything from her heart and she's incredibly brave and authentic. It's a very rare thing to come across.''
