Miley Cyrus' ex-boyfriend Justin Gaston is expecting his second child with his actress wife Melissa Ordway.

The Young and the Restless soap star is pregnant with a sibling for the couple's 14-month-old daughter Olivia.

"Justin and I are thrilled about the arrival of Baby Gaston number two," the 34-year-old tells People.com. "Our daughter Olivia is the joy and light of our lives and we cannot wait to see her become a big sister. We feel so blessed!"

Ordway is due to give birth in January (18).

She and model/singer Justin wed in 2012. He previously dated Wrecking Ball hitmaker Miley for nine months in 2009.
