The beautiful model posted the picture on her Instagram page last week, along with the caption: "Cheeeeeeze!"
She can be seen with her face pressed up against 8-month-old Bash's, as the pair both smile widely for he camera.
30-year-old Amber also appears to have ditched the foundation she usually wears, in favour of a fresh face.
Meanwhile, baby Bash looks like he has his winning smile perfected, as he kicks back in a stripy top next to his mum.
Amber and her husband, rapper Wiz Khalifa, welcomed their first child into the world in February and the new parents seem to be loving their new responsibilities.
At first, the couple took a leaf out of Beyoncé's book and chose not reveal Sebastian's adorable face to their fans.
However, (lucky for us!) they now can't help showing off how sweet their little son is.
Wiz even posted a super cute video of Sebastian drinking out of a red cup over the weekend. He wrote the caption: "Shabba dabba doobie" and can be heard giggling in the background while his tiny tot makes our hearts melt by pulling funny faces.
