The 'Come On Over' singer - whose ex-husband is singer Nick Lachey, with who she starred in MTV reality show 'Newlyweds' - insists she "loves" American football player Tony, but doesn't know if she is ready to tie the knot with him just yet.

She said: "We've been together for seven to almost eight months now. I don't really know about wedding bells - I still love him, and I'm still with him, so that's a good sign."
Jessica also spoke about her sister Ashlee, who recently announced she is expecting her first child with husband Pete Wentz.

She added to US TV show 'The View': "Ashlee sent me a picture of her belly recently. She's popping, it's so cute!"

The 27-year-old singer recently revealed making her debut country record so much she never intends to return to pop music.

She said: "I'm planning on making country music for the rest of my life, and I don't want to go back to that other world."

Jessica will be performing at the Country Thunder USA music festival, which takes place from July 16 to 19 in Wisconsin. Other artists attending the event include Carrie Underwood (her current boyfriend's ex), Taylor Swift and Sara Evans.
