For some time, the A-list couple was able to keep plenty of privacy from the start of their relationship to their journey to parenthood.

Back in May, sources confirmed to E! News that she was expecting her first child with Brody. However, the couple did not publicly discuss any details regarding Meester's pregnancy.

In July, fans were only able to find out about that Meester is soon giving birth when she was spotted grabbing a bite to eat in Los Angeles with a close friend. Apparently, the "Gossip Girl" star wore a basic white tank top and comfy striped pants that highlighted her glowing baby bump.

While the lovebirds made an agreement not to discuss their relationship publicly, there was a time when Meester discussed her goals in relation to her marriage with Brody. According to the A-list star, she wanted to nurture her personal life, family and friends whom she holds very dear to her heart.

Meester and Brody's hush-hush relationship, however, is no surprise to loyal fans anymore as the couple maintained from the very beginning of their relationship that they would not publicly discussed anything about their relationship.

In February 2014, the couple held a private wedding after keeping their romantic affair as a secret to the public eye. Meester and Brody costarred in 2011's "The Oranges" and 2014's "Life Partners" before people discovered their brewing romance.
