Remember Back in **vember, when Adam Levine shared a photo of his massive mermaid back tattoo? Well, that design Just got a Whole lot bigger. On Monday, the Maroon 5 frontman uploaded a photo on Instagram proudly showing off his new and improved ink, writing, "6 months in the making. Thanks @bryanrandolph for absolutely blowing my mind with this one! Woooo hooooo!!!!" From the looks of it, Adam had some previous work covered up, including a paw print on his right shoulder that had the words "Frankie Girl" written underneath it, which was reportedly a tribute to his dog.
