The former Xscape singer lodged court papers to end her six-year marriage to the 36-year-old hip-hop star in Georgia on December 7, but news of their split only surfaced on December 27.
They have yet to formally address the break-up in public and put their differences aside to enjoy the holidays together.
Now it appears TI and Tiny are back on good terms after recently enjoying dinner together with their baby daughter Heiress, reported Contactmusic.
Tiny shared video footage of the doting dad feeding the pair's 10-month-old baby girl a lemon on Instagram, and added the caption, "Daddy trying to teach @heiressdharris a lesson cause she wanna eat every damn thing! She showed him!! Lol (laugh out loud)".
The rapper began dating Cottle in 2001, and they tied the knot in 2010.
The couple has three children together - 12-year-old King, eight-year-old Major, and little Heiress, while TI, real name Clifford Harris, has three other kids from previous relationships, and Tameka is also mother to 20-year-old Zonnique Pullins from a prior romance.
