Happy to share a few vacation pics, Demi Lovato posted snapshots from the beach on Tuesday (January 14).

The former "X Factor" judge took to her Instagram account with the photos, while rocking a sexy black bikini.

"2014... feeling healthy, feeling rested.. Y'all ain't ready!!!! #NEONLIGHTSTOUR," Demi captioned the pic while soaking up the sun next to the sparkling blue water.

In another selfie, the 21-year-old singer flashed a smile while wearing sunglasses and showing her multicolor locks, writing, "Too much swimming = silver hair.... And I don't hate it...."

Meanwhile, Miss Lovato has been dealing with some backlash follow her absence at the 2014 People's Choice Awards.

Determined to clear the air, the "Heart Attack" hitmaker responded to the critics on Twitter by stating, "Damn... Just hopped online to check twitter and some 'fans' are being really mean :(, I'm not a the PCA's because as I have stated before, I'm taking as much time off this month as possible."

"I haven't taken a substantial amount of time off in a long time and now I am. Thank you for those who voted and understand why I am away," she added.
