"It can be intense sometimes because," revealed Katie, 32, to Ellen. "Recently I took her to get ice cream at this place in New York called Serendipity that we go to all the time. 

"It's for kids, the clientele is children," she explained. "We go in and we're waiting for a table,  and she grabs some gummies that are 'boy part' gummies, and I was horrified!"

"Boy part?" asks an astonished Ellen.

"P-E-N-I-S gummies," spelled out a smirking Holmes as the audience breaks down into laughter. "And I was like 'Oh, OK, oh wow, I said 'Those aren't Swedish fish."

'Even I know that. I know the difference there," joked Ellen.

"P-E-N-I-S gummies, and they look like it," repeated The Kennedys star bashfully, "She was holding the box, and I was like, 'Wow, we don't need that right now,' because I thought if I said, 'Put that back,' then she's going to say,'What is it?' and I don't really want to have that conversation!

'I thought, 'Why are they selling these here?' because this is for kids. Then it was on the cover of a magazine that I was giving her those gummies.  They were taking photos of it. I was like,' Yeah...no, we put them back,'" Katie explained, waving her arms in frustration.
