'Glee' Star Heather Morris -- Look I'm Pregnant Too!

With all the commotion over Halle Berry's pregnancy bombshell ... it was easy to miss that "Glee" star Heather Morris got knocked up too -- so she's letting her baby belly speak for her.

The 26-year-old showed off her growing bump -- which is about 3 months along -- in L.A. Saturday ... for the first time since announcing she and BF Taylor Hubbell were expecting a kid last week.

No word whether the pregnancy will show up in any "Glee" storylines, but at this point ... it's not like it could make the show worse.
