Jessica Simpson's Billy Songs

Jessica Simpson is recording a song with her boyfriend.

The 29-year-old singer-and-actress - who has been dating Smashing Pumpkins frontman Billy Corgan since late last year - has taken their relationship into her professional life after pictures appeared on twitter of the blonde beauty in the recording studio with the rocker and producer Kerry Brown.

After Kerry posted the picture - believed to be taken as Jessica works on her new album - the star wrote of Billy, "He braids my prayers."

'The Dukes of Hazzard' star seemed to be enjoying herself in the studio too as she wrote back: "Fun to be lost in laughter," and then later adding: "I am blessed."

Jessica - who was previously married to Nick Lachey and has dated singer John Mayer and American footballer Tony Romo - and Billy, 42, were first romantically linked in November after they both attended a Los Angeles party, though they have been friends for some time.

A source said: "She has completely fallen for Billy and his easygoing, smart attitude. She says she wants to take things a lot further.

"She had secretly been crushing on him for months and felt there was a connection at the party.

"As the night went on things got more intense and they talked with their faces just inches apart."
