Tiffani Thiessen's new baby may come way before fans expect it.

People reported that Tiffani's daughter, Harper Smith, is eager to have a brother or sister soon. People further reported that in an interview with "Sweden With Love," Tiffani planned to give Harper a sibling a long time ago. However, she halted the Tiffani Thiessen's new baby plans on when she learned that her another actress from her show, "White Collar" was expecting.

The actress said in the interview:

"We were going to try two years ago because I was thinking I'd like them to be three years apart, but my costar on the show got pregnant,"

"I thought I couldn't do that to the show. So we ended up waiting."

Harper may not have to wait for long for a new brother or sister. Tiffani and husband, Brady Smith, are definitely working on bringing another addition to the family.

The actress commented about the excitement her daughter brings about everyday for having another Tiffani Thiessen and Brady Smith baby soon.

As reported by People, Tiffani said:

"She puts more pressure on me than anyone! Every day she begs me to have a baby."

"Every morning she wakes up and says, 'Is there a baby in your belly?' She thinks it grows overnight while we're sleeping. Then she would look at me and would say, 'You're not growing a baby, Mommy!' "

The actress hoped her pregnancy would come easy as it did when she got pregnant with her first child:

"With Harper, it happened right away so I'm hoping it'll be as easy this time around."
