Pregnant Tiffani Thiessen is past her due date.

"We briefly chatted last week and she is ready to pop," her former Saved by the Bell co-star Mark-Paul Gosselaar, 36, told at the Disney/A Time for Heroes Picnic (to benefit the Elizabeth Glaser Pediatric AIDS foundation) in L.A. Sunday.

"I remember when my wife was going through this stage," added Gosselaar, who is dad to Michael, 6, and Ava, 4, with Lisa Ann Russell, whom he separated from earlier this month. "It's not a fun stage for the women or the men involved, but definitely not for the women, so I wish her nothing but the best."

Gosselaar says Thiessen, 36, and her husband, Brady Smith, "will make great parents."

Thiessen, who stars on White Collar, has said she is going to "give a Girl Scout effort to hypnobirthing," which means she'll use self-hypnosis to stay calm while delivering.

"I'm really excited about it," she told Pregnancy magazine. "That's my plan, but my husband and I are both very, very open to however the child is supposed to come out. Knock on wood it all goes well. I'm not one to judge any woman on how they choose to give birth. It's individual and I think everyone's different."
