Sharon Osbourne got emotional while talking about her son Jack's MS diagnosis earlier in the day on "The Talk," but she was showing a more determined side by the time she appeared on "Conan" (weeknights, 11 p.m. ET on TBS) Tuesday night.

News that Jack Osbourne has been diagnosed with multiple sclerosis broke earlier this week. He reportedly went in for some tests after noticing tingling in his extremities and a severe loss of vision in one eye. One doctor told "Today" that due to Osbourne's young age and how early this was caught, treatments could prove very effective in helping him live a long and healthy life.

Sharon Osbourne was confident in her son's chances of fighting MS on "Conan." "He is so strong and so positive," she said. "And, yes, my son will conquer!"

Sharon Osbourne can be seen weekdays on "The Talk" and as a judge on "America's Got Talent," Mondays and Tuesdays at 8 p.m. ET on NBC. "Conan" airs weeknights at 11 p.m. ET on TBS.
