Congrats to Ozzy Osbourne, as the Prince of Darkness has another grandchild on the way! His son Jack appears in an Instagram mirror selfie uploaded by his wife Lisa where she is shown rocking the metal horns over an obvious baby bump.

“Literally ate the biggest burrito ever,” she joked in the caption on the post, which went up yesterday (Aug. 28). This will be baby number three for the couple, who have two daughters, aged five and two.

Following the Black Sabbath farewell tour earlier this year which came to a close in the band's hometown of Birmingham, England, Ozzy got right back on the road doing solo dates, re-enlisting guitarist Zakk Wylde. He's got three dates left to close out the year -- Sep. 30 at the Louder Than Life Festival in Louisville, Ky., Oct. 22 at Monster Energy Aftershock Festival in Sacramento, Calif. and Nov. 4 at the Ozzfest Meets Knotfest event in San Bernadino, Calif.

Earlier this month (Aug. 21) Ozzy performed at Moonstock, which took place in Carterville, Ill., a part of the U.S. that experienced the longest duration of the solar eclipse. During the two minutes and forty-one second eclipse, Ozzy performed his single "Bark at the Moon" as the moon obscured the sun and plunged the festival into darkness.
