Amanda Seyfried’s movie ‘A Million Ways To Die In the West’ is coming out soon and the actress is busy promoting her movie when she’s not ‘sucking Neil Patrick Harris’ mustache!’ Seyfried sat down for an interview on The Ellen DeGeneres Show, which aired today Friday May 16, where she talked about her boyfriend of almost one year, Justin Long, as well as her movie ‘A Million Ways To Die In the West,’ which hits theaters on May 30!

Seyfried talked to Ellen about sucking on ‘A Million Ways To Die In the West’ co-star Neil Patrick Harris‘ mustache in the movie.

Seyfried said, “Oh God. I’ve never seen it in a movie. I’ve never seen it done. I had to do it. It was awful. It’s not his real mustache. It’s a fake. It’s someone else’s mustache and that’s disgusting. So, that sucks.”

The ‘Mamma Mia’ actress talked about boyfriend Justin Long, saying that they "do everything together."

“We do everything together. But, we don’t do much,” Seyfried said. “We walk my dog. And we have, we make these smoothies in the morning they’re called ‘Greenies.’ He got me onto that. Super healthy. And then we watch The Bachelor and The Bachelorette.”

"We watch 'em ... all," she continued. "In fact, it's kind of a big week next week. Anyone a fan of Andi [Dorfman]? [The season] is about to start, it's about to blow your mind. I'm so excited about it, I'm telling you."

When Ellen asked Seyfried why she loves the dating show so much, Seyfried responded that she enjoys a good "train wreck."

"I feel really guilty about it sometimes and then other times, you really want [these people] to be happy and find love. Maybe not so much the last season," Seyfried said, referring to Juan Pablo Galavis.

Seyfried's best friend Rachel McDowall is engaged to a former "Bachelorette" contestant, Constantine Tzortzis, and the couple is getting married this weekend!
