The Capital London Breakfast show host tweeted thanks to fragrance giants Coty yesterday (10 September) after receiving some of their gorgeous celebrity perfumes...
"Thank you for the perfumes! #KatyPerry my fav!" Lisa posted.
Now, it may seem funny for a celebrity to wear another celebrity's fragrance, but why the devil not?
Killer Queen, from £22.99, theperfumeshop.com is a sexy little floriental fragrance (a cross between a floral and oriental scent) that launched in the UK just last month (28 August).
It's Katy's third fragrance, following the fabulously named Purr and Meow – none of which would smell out of place on a discerning A-lister!
And it's not just Lisa who's been tempted by the world of celebrity fragrances...
We also know that actress and singer Martine McCutcheon loves Jennifer Lopez's JLo Glow After Dark, from £9.95, amazon.co.uk, while former TOWIE girl Lydia Bright is a big fan of Sarah Jessica Parker's fruity fragrance SJP NYC, from £14.50, boots.com!
Whoever said celebrity fragrances were rubbish and only loved by teenagers?
Not these ladies, that's for sure!
