Fans are thrilled to see Jessica Simpson looking so happy after a series of bizarre public appearances.

For Father's Day, the blonde beauty posted a throwback photo with her hubby Eric Johnson and their two kids, Maxwell, 5, and Ace, 3 — which appears to have been taken at the fashion designer's 2014 wedding.

She also revealed what she wrote to her husband: "Everyday is a blessing because God understood my heart and knew my future … Your Love … Your Guidance … Your Passion … Your Soul … Your way to be the best father to our children … Thank you for the everyday kind of love I have always prayed for."

The thoughtful note came just weeks after the 36-year-old made headlines over her seemingly "drunk" guest spot on The Ellen DeGeneres Show. A source told In Touch that Jessica has been having a tough time dealing with her father Joe Simpson's cancer battle, though he's now cancer free.

"Jessica is reviving her music career, her fashion empire continues to thrive, she has a husband who loves her, and two of the cutest children in Hollywood, but she's blowing it all due to her self-doubt and drug and alcohol issues," the source said, adding that she has turned to binge eating.

It doesn't help that the actress is mixing anxiety pills with liquor. "The combination of the meds and drinking scotch and vodka has [sometimes] made her disoriented. It's very sad to see her in such a state," the source explained.

This isn't the only controversy that Jess has faced in recent months. The singer has been slammed multiple times for "sexualizing" her daughter on Instagram. One follower said the tot looked like she was "trying out for the cover of Playboy" while modeling a mermaid costume.
