Andy Murray has joined seven of the world's top 13 in confirming his participation in the Aegon Championships at Queen's Club this summer.
Rafael Nadal, Milos Raonic, Stanislas Wawrinka, Marin Cilic, Grigor Dimitrov, Feliciano Lopez and Gilles Simon are among the players who will join the Brit in continuing their preparations for Wimbledon in June.
"To see such a strong, confirmed entry for the Aegon Championships is a huge thrill for everyone involved in the tournament, and fantastic news for our ticket-holders," tournament director Stephen Farrow said in a statement.
"The Aegon Championships is an ATP 500 event for the first time this year, and we are determined to exceed the standards we set in being voted ATP-250 tournament of the year by the players the past two years."
Dimitrov defeated Lopez in the 2014 final.
