The odd couple: Amy Winehouse gets a visit from Big Brother Z-lister Aisleyne

Blonde Aisleyne arrived at Amy's Camden home at 1.30am last night, accompanied by a male friend.

Dressed in typically revealing style, in a backless black dress, studded with bling, Aisleyne looked somewhat worse for wear.

She's not known to be an acquaintance of the Rehab star, and her appearance looked like something of a surprise to the singer, who answered the door in just her bra and a pair of shorts.

Aisleyne, who was a housemate in BB7, stopped off at Amy's house after attending the launch of London Restaurant Week, so she clearly wasn't looking for a bite to eat.

Amy hastily ushered Aisleyne and her friend inside, perhaps realising that answering the door in her trademark bra may not be the best idea.

But one can only guess at what common ground they shared as the odd couple got to know one another.

Aisleyne's post Big Brother career hasn't exactly been stellar. But she recently launched a clothing range (expect more of the above) and has her own cable television show called, "Aisleyne".

Maybe she was round at Amy's seeking converts to the No Smoking Day campaign she's currently fronting.

Aisleyne said recently: "Millions of people may have watched me smoke my first-ever cigarette live on Big Brother, but what no one saw was my struggle to quit after the cameras stopped rolling." Quite.

Notorious chain-smoker Amy might be a hard nut to crack though.

Last night the ex-BB housemate seemed to have another mountain to climb, as she dropped her cash on the floor and struggled to pick it up.

She didn't emerge from Amy's open-all-hours Camden home around 5.30am, so clearly they got on famously.

Perhaps Amy was celebrating making it on time to see her incarcerated husband Blake Fielder-Civil in Pentonville prison. And the fact that her "scabby" skin was finally starting to looking much healthier.

The singer's recent facial problems have been worrying fans, almost as much as the scratch marks on her arms.

The star is said to be under pressure to clean up her act, as Blake is furious about her poor time-keeping and frequent no-shows.
