The figures were first unveiled around two years ago at the central London tourist attraction, reports the Telegraph. Cyrus, 17, has been criticised in the past for posting provocative pictures of herself online.
Efron, 22, who made his name as the heartthrob on High School Musical, has recently taken on more mature roles. His most recent film is the title role in 'Charlie St Cloud," which received a lukewarm reception from critics.
London (ANI): Zac Efron and Miley Cyrus, who entered Madame Tussauds as teenage actors, have been given makeovers with their waxworks giving a more adult look. 'High School Musical" star Efron has ditched his original basketball strip for a suit and tie and Cyrus has swapped skinny jeans for a more glamorous silver, sequinned dress.
