Tennis greats Serena and Venus Williams will take on rugby stars Julian and Ardie Savea in a charity mixed doubles match before the ASB Classic next month.
The American sisters, who are both former world number ones and between them boast 29 grand slam singles titles, will be in New Zealand for the joint ATP and WTA outdoor hard court event in Auckland.
They are due to put the All Blacks' Savea brothers through their paces on centre court to raise money towards earthquake rebuilding efforts.
"It's not a bad little sibling match-up," ASB Classic director Karl Budge was quoted as telling 1 News.
"I'm not sure what the girls' rugby skills are like or the boys' tennis skills.
"There will probably be a bit of a dance-off between them at some point, too.
"I think it will be fun, it's one of those uniquely Kiwi things.
"Venus is probably the most easy person in the world to do these things with. Both of them have been awesome with it."
Together, Venus and Serena have won 14 women's doubles grand slam titles.
