Shakira's son is ''dark-haired and weighs 6lbs''.

The 'She Wolf' singer gave birth to her first child Milan Pique Mebarak with footballer boyfriend Gerard Pique on Tuesday (22.01.13) and the 25-year-old hunk's grandfather, Amador Bernabeu, has given a clue as to what the newborn looks like.

He told Catalan radio station RAC-1: ''I still haven't seen (Milan) in person but I know he is dark-haired and weights six lbs.''

Columbian President Juan Manuel Santos was among the first of well-wishers to congratulate them, tweeting: ''Congratulations to @ shakira and @ 3gerardpique on behalf of Colombia and my family on the birth of the baby.(sic)''

Floods of messages followed Juan's, with Manchester City striker Sergio 'Kun' Aguero posting: ''Welcome Milan Piqué Mebarak and congratulations to Shakira and Gerard Pique. What would you prefer as a present for the baby, a microphone or some (soccer) boots?(sic)''

Gerard's Barcelona teammate Cesc Fabregas tweeted a welcome to the baby, saying: ''can't wait to meet you.(sic)''

The Pies Descalzos (Shoeless) Foundation for deprived children, which was set up by Shakira in 1997, sent a message reading: ''The children and Pies Descalzos team are happy for Milan's birth. We love you Shakira! (sic)''

The 35-year-old beauty - whose full name is Shakira Isabel Mebarak Ripoll - appealed for support from fans prior to being admitted into the Teknon clinic, where she gave birth.

She requested: ''I'd like to ask you all to accompany me in your prayers on this very important day of my life. Shak''
