Neil Patrick Harris has been dating David Burtka for the past 10 years, and the How I Met Your Mother star's fiancé just dished on his lover, including some enticing comments about his body.

Harris graced the cover of Rolling Stone where he was wearing nothing except for a bow tie and a top hat over his pelvis. The actor has been very popular lately, especially with his Broadway work as the leading role in Hedwig and the Angry Inch. Apparently, the performer had to lose a bunch of weight for the part and gain massive abs, which left his fiancé talking.

"He's so skinny, and I think that really gives him power," Burtka said. "His body is crazy right now."

The actor's boyfriend then revealed that Harris is actually a masculine guy, which made it a challenge for him to play the transsexual role of Hedwig in the musical.

"I didn't think he could pull off the femininity of [the role]," Burtka said. "This is such a stretch for him. In his day-to-day, he's not a very feminine guy."

Harris also spoke to the magazine about his coming out to the public, which actually helped his career rather than damage it.

"Once all the cards were on the table, I got more opportunities than ever," he said. "Some actors don't get hired because you can't look into their soul and see what they're like because they're kept guarded."
