Gabrielle Union looked gorgeous when she walked through Los Angeles International Airport last night, and she smiled when asked to show off engagement ring from fiance Dwyane Wade. Not only does the Miami Heat star have great taste in women, but that ring is stunning!

Gabrielle didn't say a word to photographers, but she kept calm when asked about the love child Dwyane fathered while the two were reportedly on a break. Well, Dwyane said they were on a break -- based on Gabby's Instagram, it doesn't really seem that way! But whatever ... water under the bridge, and rumor has it she's pregnant with the NBA baller's baby.

“Gabby and her fiance Dwyane have been open about having children, and now that a wedding is around the corner, now is as good a time as ever,” a source told MediaTakeOut.

But who cares about whether she was showing off a tiny baby bump last night ... we can't stop staring at her rock:
