Gwen Stefani takes eldest son to watch friend Roger Federer's match

London, Mar 18 (ANI): Gwen Stefani took her son Kingston along to watch her friend Roger Federer play against Juan Martin Del Potro at the Indian Wells ATP tennis tournament in California.

While 42-year-old singer was present with her eldest son, rocker hubby Gavin Rossdale and their youngest son, Zuma, were nowhere to be seen, the Daily Mail reported.

Mother and son's fun day out seemed to be more nail-biting stuff than easy watching, as despite the Swiss sportsman winning the quarter final stages 6-3 and 6-2, the tot - who was flaunting reddish tresses after previously sporting blonde and then more recently dark brown locks- was clearly finding it all too much to watch, clasping his head in between his hands.

Stefani embraced him as they sat in a stadium suite with Federer's wife, Mirka and friend Mary Joe Fernandez, who is married to the tennis player's agent.

The singer looked effortlessly slender in white trousers with pinstripe detail, teamed with a scoop neck vest and her hair piled high on her head. (ANI)
