Jack and Lisa Osbourne Go Glamorous on the Red Carpet

What a view!

The day after Jack and Lisa Osbourne announced they were expecting another baby, the parents-to-be stepped out for the 23rd annual Elton John AIDS Foundation Academy Awards Viewing Party on Sunday night in West Hollywood.

“Mom & dad + 1 uterus squatter ready for the party,” Lisa, 28, captioned a photo of the couple.

While the dad-to-be, 29, looked dapper in a black suit and tie, his wife wore a coordinating black gown that showed off her baby belly, paired with a diamond necklace, earrings and a butterfly ring.

“Freezing cold with all this ice on my skin,” she joked on Instagram, snapping a picture of her statement jewelry.

And although the duo left 2½-year-old daughter Pearl Clementine at home, the evening was still a fun, family affair: Joining the couple were Jack’s parents, Ozzy and Sharon Osbourne.

“[I’m] so, so happy!” The Talk cohost told PEOPLE of the family’s future addition, due in June. “This will be our second and babies change everything, they just make everything better.”

As they walked the press line, the family of four stopped to rub Lisa’s burgeoning bump and pose for photos.

Lisa Osbourne is gorgeous–she looks like one of the “best dressed,” especially considering she is pregnant. Best wishes to them!

Karen- Sadly, from what I’ve read, Ozzy basically has nothing to do with his older kids (or their kids). 😦

Anonymous that is not true. He is in Louis and Jessicas lives. They just want to be out of the spotlight, like Aimee…

Hea on

They make a cute couple and one can clearly see that Sharon is thrilled.

Simply a stunning woman! Congratulations on the new addition to your beautiful family Jack and Lisa ❤
