As Nicki Minaj turned 33 on Tuesday, her boyfriend Meek Mill posted on Instagram a sweet birthday message alongside a cheeky image of the two.

The 28-year-old hip hop artist posted a picture showing him staring at the "Anaconda" hitmaker's breasts, reports aceshowbiz.com.

"Happy birthday to the strongest softest woman I know my baby! @nickiminaj," Mill wrote alongside the picture.

In the photograph, a scantily clad Minaj can be seen getting out of a black car while Mill stands next to it, staring at her girlfriend's breasts.

It's unclear why Mill opted to post the photograph alongside his birthday message for his girlfriend and it wasn't the first time Mill was pictured staring at Minaj's assets.

Last month, the "Superbass" hitmaker posted on the social media an image of him taking a peek at her breasts during the 2015 American Music Awards.
