London: Australian No.1 Nick Kyrgios will return to the Queen's Club tournament ahead of Wimbledon.
The controversial 24-year-old, and two-time champion Marin Cilic, are the latest big names to commit to the tournament.

Kyrgios' conduct at Queen's has overshadowed his tennis over the past two years.
In 2018 he was fined $A25,182 for making a lewd gesture with a water bottle, and last year's histrionics over two matches in one day cost him $27,000.
In the first he accused a line judge of "rigging the game" and mocked and swore at umpire Fergus Murphy, and in the second he smashed a ball out of the stadium.
Kyrgios reached the last 16 of the Australian Open in January, losing in four sets to Rafael Nadal. He made the semi-finals at Queen's in 2018.
Kyrgios and Cilic, the winner in 2012 and 2018, join Daniil Medvedev, Stefanos Tsitsipas, defending champion Feliciano Lopez and, fitness permitting, Britain's Andy Murray in committing to play the event in June.
"I love playing on grass, and the Queen's Club courts are as good as any in the world," Cilic, the world No.37, said.
"I'd love to go deep at the Fever-Tree Championships and at Wimbledon this year. I've been playing well, so I'm pumped for what's to come."
Meantime John Millman isn't feeling any extra responsibility to carry Australia through the Davis Cup tie against Brazil, which begins on Friday in Adelaide.
With Alex de Minaur and Kyrgios injured, the world No.43 Millman will be Australia's highest-ranked player in the tie.
"I have always been someone that when I go on court I just try to control the controllables and give it everything, whatever number I play or whatever role I'm given," the 30-year-old Millman said.
"I just try to do that to the best of my ability.
"But I'm getting old now and none of that fazes me too much."
Australia captain Lleyton Hewitt has yet to announce roles for the qualifying tie with the winner to advance to the cup finals in Spain in November.
Millman is joined in the team by James Duckworth, Jordan Thompson, Alex Bolt and John Peers.
"I don't think any spot is necessarily guaranteed, I don't think my spot is locked," Millman said.
"That is a really good thing in the team, that we have got a bit of flexibility and we have got a lot of guys who are playing some pretty good tennis that can put their hands.
"That captain is playing his cards close to his chest but that's not too dissimilar to any of the other ties."
Millman has recovered from a calf injury suffered at the Australian Open in January and said he was primed to perform in the cup tie.
"Any chance to play for Australia, it's the pinnacle of our sport so it's something that I really look forward to each year," he said.
"Tennis can be a bit brutal ... there is always only ever one winner and you want to be on that good side of things.
"But there's added incentive when you're playing your home tie, in front of your home crowd, that extra drive to represent your country to the best of your ability."
