Maltby voiced her support for the pair in a comment on Hyland's photo.
"@alissab6 are you kidding me?! I ship this couple SO hard! I've never seen Wells so giddy and happy! Try spreading some love instead of knocking down the cutest and most genuine coupling I've seen in a long time," she wrote.
Hyland and Adams were first linked in October after they celebrated an early Halloween together.
Sources told Us Weekly the stars have "seeing each other for months," while People confirmed the pair have developed a romance.
"They've been friends for a while and now they've been hanging out and spending more time together," an insider said. "They're flirty."
