Celebrities joined in on wishing Jude a happy birthday, including actor Vance Larena and beauty queens Michelle Dee and Aya Fernandez.

Jude is Markus's child with his partner of two years, actress Janella Salvador.

The couple, both 23, introduced their son to the public back in January, through a vlog post titled "Hey, Jude".

As seen in the vlog, Jude was born on October 20, 2020 in the United Kingdom, where Markus was born and raised.

In a previous interview, Markus shared how his life changed the moment he laid his eyes on their son.

"The moment na I saw him parang a whole wave just took over my body na parang lahat ng priorities ko ay nawala, went out of the window. Like everything is now for him, forever will be for this little man that I'm holding in my arms,” the actor said.

“And hindi ako naiyak, hindi ako natawa, parang nakatulala lang ako, nakakatitig sa kanya for hours. Like until now his smiles are the most beautiful thing in the world. Lahat ng hirap, lahat ng early morning wake up, sobrang worth it kapag nakita ko ang mukha niya. It's all about him na. It's crazy," he added.

Meanwhile, in an Instagram post last Father's Day, Janella thanked Markus for being an amazing and hands-on father to their baby boy.

"October 29, 2020: About a week after Jude was born, you had to fly back home to the Philippines alone and leave us for a month to shoot for a film. We brought you to the airport and as soon as we arrived, I saw the extreme sadness in your eyes. I actually cried during the car ride home without you. It felt surreal, you having to leave your son right after he was born. But you did it for him. You always do," she said.

"Thank you for being the most amazing, hard-working, present and hands-on father to Jude. I couldn’t be more thankful that I'm going through this crazy parenthood chapter of life with you. Happy Father’s Day, booba-boo," she added.
