When a caller asked the actress if the kiss was planned, Berry immediately said no.
"That was not planned. I knew nothing about it," she responded, then looked at host Andy Cohen to ask, "Can I say it for real?"
After Cohen's nod of approval, Berry got real candid.
"I was like, 'What the f-ck is happening right now?!' That is what was going through my mind. I was there the year before and I know the feeling of being out of your body. I just f-cking went with it. I was like, 'What the f-ck if going on right now?!'"
Cohen grilled her about the quality of the smooch, but Berry said she was "too focused on 'What the f-ck is going on right now?!' I don't even know."
See the clip below to relive the epic Oscar moment.
Berry, who famously downed an entire glass of whisky at this year's Comic-Con, said the experience was "fun in the moment" but that she "had a hard way to go the rest of the day."
"Channing Tatum dared me, and I'm a girl that you don't dare me to do something 'cause I always take it," she said. "I always take it."
Cohen then asked the Oscar winner about the pregnancy rumors that began circulating after Berry posed holding her belly on a red carpet earlier this year.
"I was not holding my stomach. Can I show you what I did?" Berry then stood up to reenact the pose. "I was on the red carpet doing my thing -- boom, boom, boom, right? My arms were down, and all of a sudden I thought, 'I'm gonna put my hands back on my hips.'"
Berry demonstrated that the "pregnancy pose" photogs caught was actually her just moving her hands from her sides to her hips.
She did, however, admit to having eaten "a pretty big lunch" consisting of "a burger and fries."
"I was a little poofed out!" she said.
A: "Well, duh, I'm gonna shag Hugh." Then Berry pleaded the fifth.
Q: Trey Songz tweeted on July 25th that he slid into your DMs. What did the message say and did you respond?
