Content creator Abel Mutua on Tuesday sent a sweet birthday message to his wife Judy Nyawira, lauding her youthfulness.

Abel joked that Nyawira would still look good in high school uniform despite her age.

"Baby!!!!! See who is not young any more. Hivyo ndio Umeondokea youth! Sasa Wewe ni Mwanamke mwenye umri wa makamo. But you're aging so well Baby.

"Wewe Hata ukishonewa uniform ya brown Ngiriambu Girls wanakuchukua intake next. Happy Birthday Mama Mumbus. I Love you!!!" he wrote.

The lovebirds have been together for 15 years and in a recent interview shared the secret behind their relationship.

Speaking to Lynn Ngugi, Mutua said his wife always keeps him in check and is his greatest support system.

"Judy is the fuel that propels me to greatness. She's been that person since 2008 when we met.

"Every situation we have been in has been a reason for me to grind even harder. Thanks to her. I keep on telling her that if it was not for her I would have amounted to nothing," said the former Tahidi High actor.

He added that Nyawira always chips in when he is broke and finances have never been a deal breaker in their union.

"She is there to remind me that it's not meant to be easy. She is always like, are you broke? I will hold you down.

"I will die for this woman any day because I know where I would have been without her...The reason why I was grounded is because I have someone in the house who was cheering for me regardless of what I was doing. As long as she saw the potential she was there to cheer me up and assure me that whatever happens, we are in it 100%," said Mutua.

Nyawira, on her part, said they have managed to stick together for 15 years because they understand their roles in the relationship.

She emphasized the importance of submission, adding that it is never about who is making more money.

"There are seasons where I was the one making more money and vice versa. It is important to understand that whatever the season yeye bado ndio the head of the house.

"We've never fought about money because pesa ni yetu sisi wote. If I am in a position to do a certain thing I will do it," she said.
