Jessica Alba may have given birth only four months ago, but the Hollywood sex symbol showed she is already back to her best as she flaunted her remarkable post-baby body on a Mexican beach.The 27-year-old looked in great shape in a black bikini as she holidayed with her husband Cash Warren and friends in Cabo San Lucas.

An avowed sports lover, the Latina star showed how she's managed to shed her pregnancy weight so quickly with a spot of beach volleyball.Alba, who welcomed daughter Honor Marie in June, recently revealed she plans to have more children.She said: ‘I'd like to have as many children as my body will allow - and I'd adopt if I still want more children after that.

‘Cash wants the same things in life. He wants to adopt and have a big family and believes in marriage forever. It can really happen if we want it to.' The actress wed sweetheart Cash, 29, in a quiet ceremony at the Beverly Hills courthouse in May.

The couple met on the set of Fantastic Four in 2004 where he was a director's assistant. Warren has since moved into producing. Alba was dressed casually in a flowing blue dress and a ponytail, and sources say that aside from courthouse staff, no one else was present at the ceremony.
