If you’re not on the Blac Chyna and Rob Kardashian train by now, act quickly before it leaves the station.

TMZ is reporting today that the controversial couple–controversial, of course, mainly to die-hard Kardashian-Jenner fans and Tyga supporters–is expecting to announce that the bun is in the oven on Mother’s Day, which is two days from now.

Rob and Chyna got together earlier this year, causing the social media stir of the year, considering Chyna’s ex-boyfriend and the father of her 3-year-old son, King, is the rapper Tyga, who is currently dating Kylie Jenner. Tyga’s been dating Kylie Jenner for over a year, and considering she just turned 18 this past August, their relationship in itself became an uncontrollable gossip snowball.

Chyna is credited by many for being the driving force behind Rob’s weight loss, which has been significant since their relationship went public. The timing of the announcement is interesting, considering Rob Kardashian has been known to have a rocky relationship with his mother, Kris Jenner.
