The “Umbrella” hitmaker – who has been single since former boyfriend Chris Brown assaulted her in February – is ready to date again, but the singer says she isn’t interested in suitors who aren’t working with a big stick between the sheets.

“He has to be good in bed and the size matters. You know what I mean? The inner beauty counts as well, but without a toy it doesn’t make it fun. Right now I don’t want to have a serious relationship, I want to have fun,” Rihanna allegedly quipped to German magazine Bravo when asked what it takes for a guy to impress her.

“At the end of the day, I’m definitely remorseful and it’s not something that I take lightly or think that it’s like under the rug,” Chris told Wendy. “I really think it’s something that is a serious matter and I’m learning from it.”

Chris will unveil the video for his new Cassie-assisted single “Crawl” on tomorrow’s Wendy.

“It was the biggest weight lifted off my chest,” she told MTV News. “If you watch the interview, you see it was a subject that I didn’t talk about for the eight months that I didn’t talk about it, so that was my first real time opening up. I had a lot of tension bottled up. So when I finally spoke about it, it felt really good. More importantly, it felt good that people got something positive out of it, because it’s devastating. It’s not fun to talk about or listen to, but there are a lot of women who are going through it, a lot of teenagers who are scared to talk about it. So I thought it was a good thing that I can be that voice for them and help them get out of that situation.”

“There was no person when I looked at him,” the 21-year-old Rihanna recalled during the second installment of an interview witg Diane Sawyer. ‘‘He had no soul in his eyes. Just blank.”

During the interview, she confirmed that Brown, 20, held her in a headlock twice and bit her on the ear and fingers the night before the 2009 Grammys last February. The attack occurred in Los Angeles’ Hancock Park neighborhood as Brown drove a rented sports car.

“I stayed. I even went back after he beat me, which was wrong,” Rihanna said. “It’s completely normal to go back. You start lying to yourself…I’ll say that to any young girl who is going through domestic violence: ‘Don’t react off of love.’”

Rihanna, 21, also hinted that it may have taken “eight or nine attempts” before she could finally leave the relationship.

“It’s pretty easy to go back….When I realized that my selfish decision for love could result in some young girl getting killed, I could not be easy with that part,” she says. “I couldn’t be responsible for that. Even if Chris never hit me again, who’s to say their boyfriend won’t? Who’s to say they won’t kill these girls? I didn’t realize how much of an impact I had on these girls’ lives until that happened.”

ABC will air more chunks of the interview on Friday’s GMA. The interview will air in its entirety Friday evening on 20/20.

The interview airs Friday at 6PM ET/PT on MTV.

The 2009 American Music Awards, live from Los Angeles, will air Nov. 22 @ 8PM on ABC.

Rihanna will sit down with Diane Sawyer in an interview that is scheduled to air on Good Morning America on Thursday, Nov. 5 and Friday, Nov. 6 @ 7AM ET — an extended interview will broadcast on Nov. 6 @ 10PM ET on the ABC newsmagazine 20/20.

“The more in love we became, the more dangerous we became for each other,” Rihanna tells Diane. “This happened to me… and it can happen to anybody. He was definitely my first big love.”

According to ABC News, Rihanna will also talk about her family life, growing up in Barbados and how life has been for her since her split from Brown, who was sentenced to five years of probation, community labor and one year of domestic violence counseling.

Rihanna’s first interview since the assault also coincides with the release of her new album, Rated R, which drops Nov. 23.
