Reese Witherspoon let fans know she is doing just fine now that summer break is over.

The "Legally Blonde" star shared a hilarious life update to her Instagram on Wednesday, posting a TikTok video in which she is fully celebrating the start of the school year.

"When the kids go back to school and you have the house to yourself," she wrote in the caption, adding three cartwheeling emojis.

The video, set to Junior Senior's "Move Your Feet," shows Witherspoon dancing in her kitchen while wearing a matching set of mustard yellow sweats.

The Oscar winner also pours herself a cup of coffee and flashes a grin from different angles before shoving her bare hand inside a funfetti cake. The video ends with her grinning widely as she shoves the huge chunk of cake into her mouth.
