This girl at work started calling me bae and boo, Is this a sign of anything or am I just overthinking things?

Ever since I started working at my job, I’ve been very friendly with this girl at work and she’s also quite a friendly person (I wouldn’t say the loudest person in the room but starts conversations whenever the room gets quiet). Now out of left field she started ending every sentence with boo or bae when she talks to me. As far as I’m aware she hasn’t did this for any other coworker, though I haven’t been working at my job for very long (Going on 2 months now). Is she just getting more comfortable around me or am I just as dense as a rock?
