The former The Only Way Is Essex star was just wearing a copy of the pop star's famous sequined bodysuit from the Toxic video.
She teamed her revealing clothing up with a platinum blonde wig in a bob style - which was decorated with the same kind of sparkles she usually reserves for her customers' nether regions.
Plugging her product, The Metro newspaper quoted Childs as saying: "I put the body vajazzle on the map so now I have created my very own Hair Vajazzle range. They add glitter and sparkle to your hair so are amazing for parties – I love them!"
Amy has her own beauty salon in Brentwood, Essex, and recently topped the last Essex rich list of TOWIE cast members with estimated earnings of £1.5m.
In case you were still wondering about the hair vajazzles, they are claimed to last for seven days after being applied with heat, and they come in two designs - heart-shaped and the normal diamante.
Sam Faiers revealed earlier this week that she has not yet decided whether to stay for another series of TOWIE.
