Aaron Paul has praised his wife Lauren as a ''gift to this planet''.

The 'Breaking Bad' actor took to Instagram to celebrate his pregnant spouse's 31st birthday on Friday (08.12.17), where he posted a picture of her showing off her burgeoning baby bump and said he would love her to ''the stars and back''.

He wrote: ''Happiest of birthdays to this mother to be. Can't wait for this precious little baby girl to be in our arms my love. What a gift you are to this planet. I love you thru the stars and back. Enjoy the day. (sic)''

The star also shared a professional photograph of himself cradling Lauren's bump, where he dubbed his spouse as ''magic''.

It was captioned: ''Had to do one more birthday post before the day is done. Just saw this incredible photo that my wife's best friend/one of my best friends @samanthamarq took of lauren and I and our future baby girl. This photo Sam! Thank you for this. Also, Happy birthday angel. You are magic. (sic)''

Aaron's kind words come after Lauren - whom he married in 2013 - recently took to social media herself to share the happy news that the child they are expecting, which is their first together, will be a girl.

Lauren shared a photo of some friends on Instagram, with a cut-out of Aaron in front and wrote: ''Nothing to say other than I love these humans and I'm missing Telluride. And I'm pleased to introduce you to Flat Aaron. When I travel without the babe, Flat Aaron always comes with and parties. Also, why are we all smiling the exact same way? It's kinda amazing. Also creepy.

''Alsooooo baby girl was in my tum here and I had no idea. BUN! (sic)''

Meanwhile, 38-year-old Aaron shared the news of Lauren's pregnancy in September by sharing another photo of her growing baby bump.

He wrote at the time: ''Hey everyone. Look what I did. Words can't express how excited I am that this little one has entered our lives. Just thought it was time I would share this beautiful news with all of you.''
