A laughing Kim Clijsters has chided former doubles star Todd Woodbridge over a text message in which he said she looked pregnant and had bigger breasts.

Woodbridge, working as an on-court TV interviewer for the Seven Network, was talking to Clijsters immediately after her 6-1, 6-3 second round win over Spain's Carla Suarez Navarro today.

He began by asking her about her outfit, which was designed by manufacturer Fila to echo the dresses worn by Australian great Evonne Goolagong.

Woodbridge then started to ask her about a promotional video when Clijsters interrupted.
