Everything she does is calculated, so what does this mean?

Blac Chyna flaunted her post-baby weight loss in a sexy black outfit as she hit the club last night, but Rob Kardashian was noticeably absent, as was her engagement ring.

They've kept everyone guessing about the status of their relationship since packing on the PDA on social media earlier this week, but we did catch the sock designer stopping by her house earlier in the day for a visit. Perhaps they had a peace talk and it didn't go so well, so she thought she'd send a message by being photographed out without her rock?

If she doesn't end up patching things up with Kimmy K's little bro, she's making sure she has a back up plan. She recently stopped by an office building to get work permits for her kids King Cairo and Dream, and she's been trying to trademark the name "Angela Kardashian" to no avail. In addition, she's set to star in the new BET show Trap Queen.

She's desperate to stay in the spotlight!
