Simpson, who has reportedly started dating singer John Mayer, hinted that she had to struggle with crippling bouts of loneliness after her divorce from Lachey.
"There are moments when I would love to fall asleep with my head on somebody's shoulder just because I was used to that for so long. I miss that," Contactmusic quoted her, as saying.
Meanwhile, recent reports suggest that Miss Simpson's dad Joe, who was not so pleased with her relation with Lachey, is extremely happy with her new choice of partner.
