Los Angeles, May 31 (IANS): Actress Amanda Bynes has praised singer Rihanna on Twitter less than a week after calling her “ugly”.

Bynes posted a mocked up photograph of them on the micro-blogging site with a message in which she called Rihanna "a beauty".

She wrote: "This is a mocked up image I found on the Internet that I LOVE! I love @Rihanna! She's such a beauty!"

While Rihanna, 25, did not respond, she tweeted the message to her followers, reports femalefirst.co.uk.

The war of words between the two stars started over the weekend when Bynes, 27, launched a bitter attack on the singer.

She tweeted: "Chris Brown beat you because you're not pretty enough," before adding: "@Rihanna no one wants to be your lover so you call everyone and their mother that I almost named my new dog Rihanna."

To that Rihanna, who recently ended her relationship with Brown, responded: "Ya see what happens when they cancel Intervention?."

This furthern angered Bynes and she wrote : "@Rihanna unlike ur fugly faced self I don't do drugs! U need the intervention dog! I met ur ugly face in person! U aren't pretty u know it. (sic)"

These tweets have since been deleted.
