Sometimes sibling rivalries can extend far beyond the teen years.
Just ask Tia Mowry-Hardrict, who jokes that she and Tamera Mowry-Housley are secretly competing to see who can get pregnant again.
"There's always this inner competition with my sister and I: who's going to have the second child first," the mother of one told People. "It would be interesting if we end up getting pregnant together—that would be crazy in a cool way."
Despite the competitive spirit, the Instant Mom star wants to pump the breaks on expanding her family for the time being. "I do want another child—and sooner rather than later—but just not now."
Even though it's something that won't happen in the immediate future, Mowry-Hardrict tells E! News she and hubby Cory Hardrict discuss it all the time. "It's definitely on the brain… It's something that we're talking about on a daily basis, so… we'll see."
