'The Originals' alum Claire Holt expecting son

Nov. 20 (UPI) -- The Originals alum Claire Holt is expecting a son with husband Andrew Joblon.

The 30-year-old Australian actress shared the news in a funny video Monday on Instagram.

The clip shows Holt and Joblon popping a balloon filled with blue confetti and captures the couple's surprised reactions.

"Gender Reveal PSA: If you are absolutely, positively certain you're having a girl, perhaps don't buy a lot of pink things and choose a name before you confirm..." Holt captioned the post.

Holt announced her pregnancy in an Instagram post in October after having a miscarriage in March.

"My heart is bursting. I'm so happy to share with you that we are having a baby! It still doesn't feel real," the star wrote.

"These past few months have been filled with excitement, anxiety, tears, joy, uncertainty but most of all gratitude. Our loss earlier this year was the darkest moment of my life," she said. "Yet, it made me infinitely more thankful for the precious baby growing inside me today."

The former Originals star previously told fans she had "never felt more broken" than after her miscarriage.

Holt is best known for playing Rebekah Mikaelson on The Vampire Diaries and The Originals. She also portrayed Samara Cook on Pretty Little Liars and Charmain Tully on Aquarius.
