In case you hadn't heard, Lauren Conrad is an absolute pro at Halloween. Unsurprisingly, she prepped for the holiday by posting holiday tips on her site, wearing the chicest creative costumes, and even taking an Instagram-worthy trip to a pumpkin patch, but alas, it was her almost 4-month-old son Liam who ended up stealing the spotlight.

Conrad posted an Instagram story on Halloween night of baby Liam in the softest looking costume, and we'd say it's a great way to ring in his first big holiday.

In the photo, Conrad poses with her son in a black cat hat with whiskers drawn on, while Liam wears a soft-looking onesie and a little dog nose filter over his face. Conrad captioned the photo with a simple well wish of "Happy Halloween!"

This isn't the first time Liam has been the star of Conrad's social media accounts. He tends to make an appearance every once in awhile, usually while he's snuggled up sleeping.

We're happy to see the little guy awake and celebrating his first-ever Halloween.

With Lauren Conrad as a mom, we'd bet that Liam will have plenty of cute costumes in his future too. Happy Halloween, little guy!
