The couple welcomed their baby in London last year.
Sharing lovely photos of him, she wrote;
”My handsome little man is ONE!
Grateful for 365 days of unspeakable joy with you. Anyone who has ever been in his presence can attest to the fact that he exudes nothing but happiness at all times. He is my solace and I’m so proud to be his mama! Happy 1st Birthday My Sonshine! May God continue to bless and keep you always”
