Lleyton Hewitt became the youngest male world number one, aged 20, in 2001

Former Wimbledon champion Lleyton Hewitt has been given a wildcard entry to the Aegon Championships at Queen's in what will be his last grass-court season.

The Australian former world number one, 33, said last month he would retire external-link after next year's Australian Open.

The 2001 US Open champion has won Queen's four times.

"Lleyton is one of our greatest champions," tournament director Stephen Farrow said.

"It is a little unconventional to award wildcards before the entry list has been finalised, but it took us roughly two seconds to decide to guarantee Lleyton a wildcard."

Hewitt will join defending champion Grigor Dimitrov of Bulgaria and British number one Andy Murray in the draw for the event, which takes place from 15 to 21 June.
