“Dude, I don’t know. I don’t know,” Christina said when asked.

She added, “I’m hoping that everything is all good with her. Everything’s beautiful. The future should be celebrated.”

Jimmy then said, “If you had to choose between being in it and not being in it?”

Christina laughed and responded, “I mean, for real? For real?”

“I would like to be in it,” Jimmy said.

“Maybe you will be in it. Listen, I’d rather it be you than me,” Christina finally said.

Well, we already know that there is a mention of Christina as some excerpts from Britney‘s book, “The Woman in Me,” were released and we have the text here.
