United Kingdom, Feb. 7 -- Jessica Simpson has been in the "best spirits" after announcing her split from Eric Johnson.

The 44-year-old singer confirmed in January that she was splitting from the former NFL star, but Jessica's sister, Ashlee Simpson, has now revealed that she's in good spirits.

Ashlee, 40, told Us Weekly: "I just did an interview with her today. She has music coming, and it was so exciting. And I'm so proud of her."

Ashley suggested that Jessica is thriving following her recent break-up.

The 'Pieces of Me' hitmaker - who is married to actor Evan Ross - shared: "We are strong little ladies, and, you know, I think that's a cool thing about life is just always growing and finding yourself, wherever that's supposed to be."...
