Former Playboy playmate Holly Madison is single again. The 'Holly's World' star and boyfriend Jack Barakat have broken up, E!Online.com reports. The couple dated for 10 months.

"I can confirm Holly and Jack are no longer dating," Holly's rep told E!Online. "Their decision to split was both mutual and amicable."

The reality TV star starting dating Barakat after flirting with him for months on Twitter. Barakat is a guitarist for Baltimore-based band All Time Low.

"We met through a mutual friend and then somehow somebody retweeted something funny he said on Twitter," she said. "So I started following him and then we started tweeting each other back and forth!" The flirtation then progressed to direct messages and led to the pair exchanging numbers.

"We were texting for months, and finally when I had my vacation, I was like, 'Do you wanna come hang out with me?' and he did and we hit it off right away," Madison said.
