Gwyneth Paltrow said kissing Robert Downey Jr. in their Marvel movies felt like she was 'kissing my brother'

• Gwyneth Paltrow revealed to Kate Hudson on her latest "Goop Podcast" that she didn't enjoy kissing Robert Downey Jr. in the Marvel movies.
• "This is literally like kissing my brother," she said.
• Hudson also revealed that kissing Matthew McConaughey in the movies she did with him wasn't always the most romantic feeling.
• "When we were kissing in the end of 'Fool's Gold,' we're in the ocean; we had the plane crash. He just had snot all over his face," Hudson said.
• Hudson did reveal that her "Almost Famous" costar Billy Crudup was a good kisser.

For Gwyneth Paltrow's "Goop Podcast" on Tuesday, she and Kate Hudson talked about their best and worst on-screen kisses.

Paltrow said her worst was Iron Man himself, Robert Downey Jr., because of the "brother energy" the two have.

"Like with Robert, when I kissed him and I was like, 'You've got to be kidding me,'" Paltrow, who locked lips with Downey in several "Iron Man" and "Avengers" movies, said. "This is literally like kissing my brother."

Both have been Hollywood lifers, as Downey's father, Robert Downey Sr., was an actor-director, and Paltrow's mother is actress Blythe Danner (her father, Bruce, was a TV and movie director-producer). They have likely been interacting in the same circles their whole lives before playing Tony Stark and Pepper Potts in the Marvel Cinematic Universe.

Hudson said her on-screen kisses haven't been the best, either. And she's been linked with Matthew McConaughey several times. But the actress said it was less a "brother energy" with McConaughey, and more the circumstances.

"The thing is, every time I kiss McConaughey, it's like there's just something happening and there's snot or wind," she told Paltrow. "When we were kissing in the end of 'Fool's Gold,' we're in the ocean; we had the plane crash. He just had snot all over his face."

But Hudson did reveal a guy who was good at kissing.

"You know who was a good kisser, but you didn't see it 'cause they cut it out? Was Billy," Hudson said of her "Almost Famous" costar, Billy Crudup. "Billy was good. That was good."

"He looked like he would be a good kisser," Paltrow said.
