The singer/actor, 41, stars as Detective Danny Reagan on the U.S. cop show and the programme, which premiered in September (10), has proved to be a critical success.
Wahlberg admits he's keen to focus more on his screen career as he grows older - so he will be working double duty as he juggles his TV responsibilities with rehearsals for his band's upcoming joint concerts with the Backstreet Boys.
He tells TV Guide magazine, "I made a strategic choice when I decided to do Blue Bloods to shift the balance to acting.
"(So) I'll wrap Blue Bloods at 8pm, then go to a studio to start preparing the (NKOTB) show till 3 or 4am. I want to do it all now, while I still can!"
