“Power” creator Courtney Kemp and Kelis know the importance of Sibling Day. The high-profile entertainers went to social media this week to acknowledge their day ones.

Both Kemp and Kelis relied on Instagram Thursday to pay their siblings some major props.

Earlier this year, Kelis blew up Instagram with slew of bikini pics.

In February, reports emerged about Kelis’ ex-husband Nas having issues with her taking their son on trips to Colombia.

Nas is pissed off about a bunch of child custody issues — the biggest being Kelis’ plans to hightail to Cartagena. According to docs, obtained by TMZ, Kelis already took 9-year-old Knight to Colombia last month. Nas says he was supposed to get their son on New Year’s Eve … but Kelis texted him to say the plan had changed. He says she didn’t come back to the states until Jan. 14. Further, he says Kelis has told him she and her new husband have a farm in Colombia and she intends to stay there. Nas says she’s already withdrawn Knight from his private school in L.A. … and he says Kelis is currently homeschooling the kid in Colombia. (TMZ)
