Kim Clijsters will work with Yanina Wickmayer during Wimbledon, but has not become her coach.
"Kim is not my new coach," announced Wickmayer, even before confirming that Clijsters would be helping her fellow Belgian during Wimbledon.
The 27-year-old Wickmayer recently stopped working with her coach, Nicolas Beuque.
Clijsters has also previously worked with another Belgian, Kirsten Flipkens, at a few events.
The four-time Grand Slam champion had been hitting with Wickmayer during the Australian Open, and will be with her at Wimbledon, Wickmayer's representatives told Belgian press.
Wickmayer is No. 95 in the rankings.
