Rob Kardashian and Blac Chyna are giving KimYe a run for their money in the romance department. Kanye, who has repeatedly called Kim his muse and showers her with expensive gifts, may have taught his brother-in-law a thing or two about being in a power couple. Apparently the couple, who are getting closer by the day, have their very own song to commemorate their love — John Legend's "The Beginning."

Remember, "the beginning" is how Chyna captioned the very first pic of the couple that set social media on fire (the one where she rested in the crook of his tattooed arm) and — in classic Kanye style — Rob had the lyrics written in diamonds on a massive $35,000 piece of art he got Chyna for Valentine's Day, along with 100 red roses. Of course, 'Ye would have had his own lyrics transcribed over a nude of his wife, but baby steps are fine, Rob.

According to the song, this is "the beginning of forever." Oh, the song also advises them to "do it till [they] have a baby."

Jokes aside, it seems like ChyRo intend to prove their love is real. Rob's friends say they've never seen him so happy. According to TMZ, Chyna isn't only inspiring him to get his body right and tight, she's revving up his appetite for success, too. Just days after he first hooked up with Chyna, Rob apparently filed legal docs to expand production on his Arthur George sock line to include belts, booties, coats, dresses, gloves, headwear, jackets, leggings, tuxedos, swimwear and underwear.

He already has the best advertising in town:

Gotta wonder if Kylie is looking over at Tyga like, "What have you done for me lately?"
