Stars, they're just like us.

During an appearance on SiriusXM's Andy Cohen Live this week, Michael Bolton shared some details on how he winded up babysitting for none other than Paula Abdul.

"So, how that happened was her older sister was dating my guitarist and I was writing songs, demoing them to try to get a record deal and in L.A.," explained Bolton, who is 10 years older than Abdul. "We wanted to go out one night and we realized we couldn't because we couldn't leave Paula - our friend's baby sister, little sister - couldn't leave her alone."
