Harper Seven Beckham has topped a list of the hottest celebrities under 25.

The eight-week-old tot - the youngest child of David and Victoria Beckham - beat a host of huge names including Lady GaGa, Blake Lively and Emma Stone to take the top spot in InStyle's Hot 100 List, thanks to her famous parents.

The British magazine said: "Will she be a pop star, designer or sportswoman? Either way, Posh's daughter inherits a Gaggle of hunky older brothers and one heck of a wardrobe."

Harper narrowly beat fellow celebrity Offspring Zuma Rossdale, three, and his five-year-old brother Kingston into second and third place respectively, while Suri Cruise, five, and nine-year-old artist Kieron Williamson - known as a "mini-Monet" - completed the top five.

Power teens Lourdes Leon, 15, Justin Bieber, 17, Saoirse Ronan, 17, and 18-year-old Miley Cyrus placed at numbers 15, 18, 19 and 20, while 'Harry Potter' actress Emma Watson could only make it to 44th position, despite high-profile contracts with Lancome and previously Burberry.

Controversial singer Lady Gaga, 25, narrowly made the list, only managing to place at number 99 ahead of 100th place 'Mamma Mia' star Amanda Seyfried.
