New York: Jennifer Garner has described shooting a sex scene with Hugh Jackman for the movie ‘Butter’ as 'horrifying'.

Garner, who was at the AFI Fest premiere of ‘Butter’ in Los Angeles, said that she's a huge fan of the X-Men star and the whole scenario was awkward because it was the first day of filming.

"Of course, it was like the first day we worked together ¦ It's always like that," a leading daily quoted her.

"It's always like, 'It's nice to meet you, now let's moan and groan,'" she said.
