Justin Timberlake and Andy Samberg seemed at ease with Lady Gaga in their hilarious "Saturday Night Live" digital short, "3-Way," but wedding dresses the singer says the two were at a loss for words when they asked her to be a part of it.

 

"I wish that they filmed the backstage cocktail dresses scenario as both Justin and Andy Samberg tried simultaneously to pitch this idea to me and they both choked on the way in," Gaga said in a radio interview with Mojo in the Morning today. 

 

"Justin was like 'Umm so umm, we have a skit idea and umm, well I'm not really good at this I'll have Andy tell you.' Then Andy came and was like 'Well umm bluh blah we have this skit idea.' Then they both came in finally and they told me the story and I'm like, 'Guys, I get it.' They're like 'We really designer wedding dresses like each other.'"

 

And even though the skit got major laughs on Saturday night, Gaga didn't get the initial joke Timberlake and Samberg were going for.

 

"I said, 'I mean I'll do it but I don't get why it's funny,'" she added. "And they're like "It's a three-way. We want to do a bridesmaid dresses plus size three-way."

 

"3-Way" is a sequel to Timberlake and Samberg's previous hit, "Motherlover."

 

In it, Timberlake and Samberg -- in really bad facial hair and '80s-era fashion -- sing the praises of having a menage a trois.

 

"It's not gay when it's in a evening dresses three-way," Timberlake and Samberg sing, with their third partner, Gaga, on backing vocals. "With a honey in the middle and some lee-way. The area is gray in a three-way."
