London, June 20 : Robbie Williams apparently went in for a makeover, for the singer was spotted flaunting chestnut-coloured locks.

The 35-year-old was seen sporting a youthful new look just days after being spotted with grey strands.

The former Take That member was also reported to have headed off for a Caribbean break with girlfriend Ayda Field.

"Perhaps he''s trying to roll back the years," The Daily Star quoted an onlooker as saying.

Robbie has been considering a 10-million pound solo comeback tour next year and is setting up a string of dates at London''s O2 arena-his first in the UK for four years, according to reports. (ANI)
