"I think we guessed that," Gloria told "Extra" at the Latin Grammys. "Either that or she swallowed a basketball!”
Jennifer and husband Marc Anthony made the announcement this week at the last concert of their tour. The baby - or babies, depending on the rumors - will be Jennifer's first.
“Jennifer and Marc are going to make wonderful parents," Gloria said. "The baby is definitely going to be talented!”
Gloria also revealed that she'll make an appearance next week on "Dancing with the Stars." Last month, Gloria had to cancel her highly-anticipated appearance after her mother fell ill.
“This Tuesday, I’ll be on to fulfill my commitment. I was really sad that I had to cancel," she admitted. "But, I had to be with my mom, no two ways about it. She was really, really ill.”
