Sigh.

Well, she's certainly looking trim too.

Alexandra Burke looks even more slim and toned now. Copyright [Alexandra Burke]We reckon Alexandra looks as though she's lost weight even since her holiday - and, trust us, we didn't think she could GET any hotter.

The singer hinted during her holiday that she was working on new material, and she's recently tweeted photos of herself getting ready for performances.

Alexandra's last album didn't do as well as expected after the singles received no airplay.

She said at the time: "Obviously it’s disappointing. But what can I do? The main thing for me is I’m proud of my music and the fans all love what I’m doing."

Well, if the music doesn't work out Alexandra could always try her hand at a fitness DVD. We're off to drool over her body.
