Looks like Tyga is unphased by recent reports of an alleged $90K tax lien.

The rapper headed out to lunch in Malibu at Mr. Chow with Blac Chyna and their son King Cairo. Kim K.'s gal pal Chyna showed off a darker look, a big switch up from her normal blonde locks. Chyna has also been busy with her lash line titled 'Lashed.'

Check out some pics of the couple above.
