Lucy, 23, was watching the ITV1 singing show during the weekend when she made her confession to her 420,000 Twitter followers.
After watching 17-year-old Luke take to the stage and perform his own rendition of the Bryan Adams hit 'Everything I Do', Lucy let her feelings be known.
"Can Luke Friend just be a big older?" she tweeted. Oo-err!
The new series of Made In Chelsea kicked off a fortnight ago and, in the first two episodes, Lucy has been very much single following her split with Spencer Matthews.

However, a teaser for tonight's episode revealed that she may have been getting down to it with fellow co-star Jamie Laing.
With her straight-talking ways and expert flirting skills, something tells us Luke just wouldn't be able to handle the Watson!
