Jessica, 33, gave birth to her second child, a boy called Ace Knute, in June but it seems she is itching to head back into the studio to lay down some tracks.
Last night (24 September), the American mum-of-two tweeted: "I need to make music."
Earlier, Jessica - who is engaged to former American football player Eric Johnson, had enjoyed a 'mums day out' with her close friend CaCee Cobb and another pal.
Since featuring in Newlyweds as Jessica's PA, CaCee has gone on to marry former Clueless actor and Scrubs star Donald Faison.
Last month, the couple welcomed their first child, a son, into the world.
Jessica shared a picture of her meet-up with CaCee with fans on Twitter, saying "Mums day out!"
