Prince Albert of Monaco's love child Alexandre Grimaldi-Coste, 18, is pictured with his flight attendant mother in Rome days after Charlene was seen with her children for the first time since November

Prince Albert of Monaco's love child Alexandre Grimaldi-Coste, 18, enjoyed dinner at top Italian restaurant in Rome last night with his flight attendant mother.

Alexandre, 18, is the child of Prince Albert and his former mistress Nicole Coste, 50,  a former Air France flight attendant from Togo.

Looking suave in a grey jumper, blue chinos and box fresh white Converses, Alexandre was the picture of casual cool as he walked through the Italian capital and ate dinner at Dal Bolognese Roma.

Albert, 64, confirmed he was the biological father of Alexandre in May 2005, just before he was enthroned as Prince of Monaco, 

As his parents never married, Alexandre is not in the line of succession to the  Monegasque throne.

Albert also has daughter Jazmin, 30, with US estate agent Tamara Rotol
