Melissa Joan Hart Is Embarrassed By Past Endorsement Deal On 'Watch What Happens: Live' (VIDEO)

When Melissa Joan Hart visited Bravo's "Watch What Happens: Live," Andy Cohen had an embarrassing blast from the past ready for her.

Hart was mortified by a highlight reel of some vintage video clips, including her commercial for Crayola’s “Jazzy Jewelry” craft kit.

"That’s before endorsing things became popular," the "Sabrina" star observed. “That was like the only thing that was an endorsement. Ugh, it’s embarrassing.” Even more embarrassing, Hart was sitting beside Khloe Kardashian, one of the undisputed queens of endorsement deals -- Hart even spritzed herself with Kardashian's perfume.

Another recent development that might've had Hart blushing is her failed Kickstarter campaign. Unlike Zach Braff's new project and the "Veronica Mars" movie, Hart failed to amass the necessary funding for a new film on the crowdsourcing site. She told the LA Times, "I really think [Kickstarter’s] more for entrepreneurs. People don't necessarily want to see already successful people becoming more successful ... It’s disappointing but hopefully we won’t always be used as an example of how not to do it."

It's not all bad news for Hart, however: She has an upcoming book, "Melissa Explains It All," and her ABC Family series "Melissa and Joey" was just renewed for Season 4.

"Watch What Happens: Live" airs weekdays at 11 p.m. ET on Bravo.
