The romance between Alex Rodriguez and Cameron Diaz is hotting up. The couple entertained a table of friends at West Village eatery The Lion on Saturday night when, a spy reports, “They arrived around 10 p.m. with a group of eight friends and sat in the private lounge upstairs. The staff took turns guarding the ropes that led to their upstairs room, which was theirs exclusively for the dinner party.” Page Six previously revealed the pair have been on a series of secret dates in the past two months.
