Watch out Lady Gaga, there's a new monster in town.

Kelly Clarkson posted a photo of her adorable baby girl River Rose in pink polka dot sunglasses, an oversize bib and pink onesie and directed the caption at the "Artpop" singer.

Since Clarkson and her husband, talent manager Brandon Blackstock, welcomed their first child on June 12, River has made an occasional appearance on her famous mom's Twitter feed.

In early September, Clarkson posted a photo of River in rhinestone-covered headphones at a Garth Brooks-Trisha Yearwood concert outside Chicago.

"Amazing show!" tweeted Clarkson. "It was River's 1st concert!"

Though the "American Idol" singer is admittedly "addicted" to her baby girl, she is also working on a new album.

"The high road can be a lonely place but I'd rather talk to my shadow than a mirage," the "Since U Been Gone" singer wrote, teasing one of her new songs.

"Things r great n my world! The song is about the high road :)" Clarkson tweeted.
