Lily Allen has joked that Jessie J only qualified for her wins at last night's (October 5) MOBO Awards because she sings “man dem” in one of her songs.

The singer dominated the MOBO Awards, which is short for Music Of Black Origin, winning four of the five awards she was nominated four.

Her wins included Best Song for 'Do It Like A Dude', which includes the lyric: “We can do it like the man'dem, man'dem.”

On Twitter, Allen, a fan of the singer, joked about her wins.

She wrote: “Now, I love Jessie J as much as the next person, but how is her music 'of black origin' ? Is it cause she says 'man dem' in her tune?”

Jessie J also used the social-networking website to thank her fans for her success.

The 2011 MOBO Awards took place in Glasgow and were hosted by Jason Derulo and Alesha Dixon. You can see the full winners list here.
