Rob Kardashian Suggests Rihanna Be His Date to Kim Kardashian's Wedding on Twitter

Rob Kardashian has no shame when it comes to flirting on Twitter. The reality star sent a flurry of flirty texts to Rihanna last night and indirectly asked the singing sensation to sister Kim Kardashian's wedding to Kris Humphries.

It all started with Rihanna Tweeting, "ugh! DUH!!! Popcorn and remote in hand," about her relaxing movie night on Monday.

"I can make this right here happen." Rob boldly Tweeted at RiRi, who fired right back with the flirty Tweet: "Its past your bedtime."

Then Rob took it to the next level, responding, "You can put me to bed" (this was after he had already Tweeted, "I need a date for my Sis @KimKardashian WEDDING!").

Is Rob getting his flirt on with Rihanna so she will be his guest at the wedding of the year? Sound off in the comments!
