(Cover) - EN Showbiz - Rihanna would reportedly be "disappointed" if Katy Perry didn't attend her wedding.

The pop star has allegedly been planning her marriage to bad-boy rapper Chris Brown. Rihanna and Chris are thought to have rekindled their romance after being spotted together in public several times recently.

The 24-year-old singer is so smitten she has reportedly planned a list of guests she'd like at their dream wedding. Rihanna now fears one in particular won't show at her nuptials as a result of the tumultuous nature of her relationship with Chris.

"Of course Katy [Perry] will be invited. She can see why Katy and plenty of her other friends can't get behind her decision. But Ri's not going to let anything affect anything," a source told British magazine Look.

"Rihanna wasn't at Katy's wedding to Russell [Brand], so it wouldn't be a shock to people if Katy doesn't turn up. But I think Rihanna would be really disappointed."

As well as Katy, other famous faces Rihanna would like at her nuptials include Stella McCartney and Jay-Z.
