The expectant mum was lavished with attention by hubby Jack, sister-in-law Kelly and mother-in-law Sharon as the whole family posed for pictures in LA.
Kelly and Sharon couldn't resist placing their hands on Lisa's baby bump - and making sure photographers saw it! Something tells us they're VERY excited to meet the new arrival!
Jack and Lisa are already parents to adorable daughter Pearl, who turned three on 24 April.
Last night's Race to Erase MS gala was an important event for the Osbourne family: Jack was diagnosed with the incurable neurological condition three years ago, just a few weeks after the birth of Pearl.
Jack has praised wife Lisa for being a pillar of strength for him.
"Lisa has been great — a real trouper. She learned everything she could about the disease. In fact, she knows as much about MS as I do! She's really good at encouraging me to take breaks and say no to professional requests when I need to slow down. She also keeps me focused and makes sure I get enough rest and exercise. I definitely wouldn't be doing as well as I am without her."
