LeBron James Is REALLY INTO His Wife . . . The Cameras Caught Him CHECKING HER OUT From Behind . . . And SMILING!!!

LeBron James and his wife Savannah celebrated their THIRD wedding anniversary last night in Los Angeles. Savannah wore a very form-fitting and revealing outfit - and looked AMAZING.

We're not the only ones that noticed how GREAT Savannah looked. Despite being with his wife for nearly 15 years, LeBron was caught checking her out . . . and SMILING.

We love these two as a couple.

LeBron married Savannah in 2013. They have three beautiful kids: Bryce Maximus James, Zhuri James and LeBron James Jr. What a perfect family.
