Los Angeles, California - Actor Blake Lively took a break from regularly trolling her hubby Ryan Reynolds to poke fun at herself on Instagram!

The heavily pregnant star kicked off the new week by flaunting a horrendous hair fail that occurred on Sunday evening.

The 35-year-old Gossip Girl alum shared a snap to her IG story of herself sporting her usual blonde tresses in such a manner that would make Serena van der Woodsen ashamed.

"How did not one person find the time to mention to me that this is what my hair looked like today?" Lively joked in the on-screen text.

The Sisterhood of the Traveling Pants actor, who wore floral pajamas in the candid snap, tagged her husband Ryan Reynolds, her sister Robin Lively, and her brother-in-law Terry Reynolds in the story, insinuating they were the culprits who didn't fill her in about her bad hair day.

Lively has been maintaining a low-profile as she awaits the arrival of her fourth child with Reynolds.

The two haven't clarified whether they are expecting a baby boy this time around as they are already parents to three girls: James, Ines, and Betty. However, her bestie Taylor Swift may have let slip the name and gender of the spouses' unborn baby.

But if Reynolds is to blame for her recent hair faux pas, the Green Lantern actor better watch his back as his wife is the queen of trolling for a reason!
