Zoe Saldana never officially confirmed her reported pregnancy, till now, when she took on the ALS Ice Bucket Challenge and her baby bump glaringly showed as she explained the challenge on video.

The 36-year-old actress filmed herself together with husband Marco Perego, telling the audience that she won't be able to do the challenge but her husband will, on her behalf.

Also, aside from nominating just three other people to take on the challenge, Saldana and Perego managed to come up with five. They challenged James Cameron, Rob Burkle, Aileen Getty, Salma Hayek, and Francois Pinault.

The video began with Saldana saying she was accepting James Gunn's challenge. However, she pointed out that she can't do it herself as she rubbed her belly showing off her baby bump. The couple enthusiastically urged the people they challenged to do it and to not forget to donate for the said fundraising campaign.

A man then carried a container with ice water and showered it on Perego. Saldana screamed as if feeling how cold the water was, followed by Perego's own scream before he jumped into the swimming pool.

The video ended with Saldana and some other people giggling. The video of the crazy challenge and Saldana proudly addressing her pregnancy below:

Saldana was wearing all black from top to bottom, which made her baby bump more evident. Her husband was wearing his hair in a man bun and donned a black shirt paired with sweatpants.

Saldana and Perego secretly wed September last year.

Saldana has recently posed for Women's Health Magazine showing her completely nude body but her bump was not showing back then.

Aside from Saldana, Justin Bieber, Taylor Swift, Selena Gomez, Nina Dobrev and a lot of other celebrities have done the ALS Ice Bucket Challenge to raise funds for the treatment of those afflicted with the disease.
