Former Phillie Lenny Dykstra is about to become a grandfather yet again.

Actress Jamie-Lynn Sigler today revealed today on social media that she is pregnant with her and husband Cutter Dykstra's second child. The couple's first son, Beau, was born in August 2013.

In an Instagram post, Sigler, 36, wrote that she took five pregnancy tests to be certain of her pregnancy. "This is the actual pic I sent my husband this past Mother's Day while lying on the bathroom floor. I had just returned from Israel, was jet lagged, and didn't believe my eyes," Sigler wrote. "So had to obviously be @Clearblue 5x over sure. We are SO excited to announce the #ClearblueConfirmed arrival of another little one in just a few short months  #clearbluepartner"

Note the image was tagged #clearbluepartner, indicating a partnership between the actress and Clearblue, a home pregnancy and fertility test company.

As Us Weekly reports, Sigler is currently about four months pregnant. However, Dykstra, 28, has known about it much longer than that. The actress told the publication that she "couldn't wait" to tell her husband about the pregnancy.

"When I peeked at it and I saw the word 'pregnant,' I screamed," Sigler said. "My husband wasn't with me, so I took five more because I knew he would want the proof."

Sigler added that Dykstra is "an amazing dad" to Beau, and is "as present as he can be."

"I couldn't have asked for more," Sigler told Us Weekly. "He's one of the most present dads I've ever seen and I'm just lucky that he's mine."

Dykstra and Sigler were in engaged in 2013, and wed in January last year. Grandpa Lenny, meanwhile, was profiled by the Inquirer's Frank Fitzpatrick last month.
