The couple put a lot of effort into making the day special for their baby girl and showed off all their hard work through photos posted on Instagram.
The celebrations started on Sunday (25 May), and Marvin and Rochelle made sure the party was fit for a princess, as they created an 'enchanted garden' theme. Aww!
Rochelle was prepping from the day before, telling fans: "Early night for me tonight... big day tomorrow, Alaia's christening and birthday party. I'm sure there's something I've forgotten to do?"
Saturdays singer Rochelle was joined by family and close friends, including her bandmate Una Foden, who arrived with her daughter Aoife Belle.
Rochelle shared plenty of photos of the special occasion, including one of Marvin holding Alaia up to blow out the candles on her cake.
Alaia looked ever so pretty in a gold and white dress, and looked to be in awe as she took in her surroundings.
After a successful party, Rochelle tweeted: "Yesterday was the most amazing day... we were so blessed."
Meanwhile, Captial FM DJ Marvin, said: "Alaia's Baptism and 1st Birthday was so so lovely yesterday! Thank you to all our family and friends plus @RevRach for an amazing service."
Baby Alaia turned one on 20 May, and enjoyed a mini pink-themed birthday breakfast at home, complete with presents and balloons!
Marvin and Rochelle couldn't stop gushing about their little bundle of joy and both took to Twitter to share some very sweet messages.
At the time, Rochelle tweeted: "Exactly a year ago at 10.05am I gave birth to my world! Happy 1st birthday to my angel Alaia..Mummy and Daddy love you so much."
Marvin added: "It's my Princess Alaia-Mai's birthday today! She is 1 year old... this has been the best year of my life she is the most adorable baby."
