Sam, who won the 10th series of the X Factor in 2013, shared the pic on her twitter page, saying: "#smileymiley loves bath time xx."
Miley certainly is very smiley indeed, maybe Sam was singing her some pitch perfect lullabies? We'd be equally as delighted!
The singer also shared this pic on Monday (13 April) tweeting: "Even with a poorly eye she still manages to give me that special smile!!! #SmileyMiley #happykid."
Aww, how cute is that?!
Sam was dropped from Simon Cowell's record label Syco back in February, but it clearly isn't getting her down.
In March, Sam told fans: "Studio today writing another new track for my album #excited."
After a chart-topping single and album, we're sure fans are excited to see what she does next.
