Penlope CruzPenelope Cruz shows off her growing baby belly at London's Heathrow Airport.

The actress was traveling with her mother and sisters, wearing a see-through top that proudly displayed her bump.

Cruz is expecting her first child with husband, fellow Oscar winner Javier Bardem.

News of the pregnancy spread when Penelope was seen on the set of 'Pirates of the Caribbean: On Stranger Tides' in a billowy top. Her rep then quickly confirmed that she was with child, despite earlier denials.

Bardem, 41, and Cruz, 36, met in 1992 on the set of 'Jamon, Jamon,' and most recently starred together in 2008's 'Vicky Cristina Barcelona,' for which the actress won her Oscar.

The couple began dating in 2007 and married in July of 2010 in a small ceremony in the Bahamas.
