Rumors have continued to fly about Jessica Simpson and Billy Corgan on the romantic front, but after a month of heavy flirting, things have reportedly cooled off.
"Jessica loved spending time in and out of the studio with Billy," a pal said of Jess and the Smashing Pumpkins frontman. "She's in awe of his musical prowess."
"It added up to serious feelings, but they are not actually dating."
The source said that Jessica Simpson and Billy Corgan were introduced by a music producer pal, and they've worked together both in New York and Los Angeles.
The insider said Corgan was making an effort to visit her beyond their musical collaboration, but that the two were probably too different for that to work.

"Dating Jessica can be intense. Billy lives a quiet, private, music-focused life and the taste of publicity he got being with Jessica was an eye opener," the source said.
"Billy likes Jessica, but he will work to keep their relationship as it is and focus on the music. They were not getting serious, but Jessica has so much fun with him."
The pal said hanging with Corgan is helping Jess "finally grow up."
"[Jessica Simpson] has gotten fed up with doing things for other people ... she barely wears makeup these days. She eats whatever she wants. She once was a slave to what people thought, but Billy has brought out a mature, toned down Jessica."
