Actress Cameron Diaz has sparked rumours that her relationship with baseball player Alex Rodriguez is back on track after they were snapped spending vacation together in Mexico.

The pair's romance, which began earlier this year, was rumoured to be over in October but they brushed off the speculation by putting on a united front during a romantic break in Mexico, reports imdb.com.

Diaz was spotted enjoying a family break with A-Rod's children, six-year-old Natasha and Ella, two.
