Jennifer Garner reveals how she accidentally bought an 'aggressive' Christmas tree

While the Rockefeller tree lights up the New York City skyline, another large Christmas tree headed to a blissfully unaware Jennifer Garner on the other side of the country.

Garner found out she made a mistake when she allowed her kids get a bigger Christmas tree this year, she shared on Instagram. It caused quite the shock when the prodigious pine arrived.

"So I told my kids we can go bigger because we're in a rental house and it has a really big foyer," explains Garner in a close-up video as she stands next to her tree. She then holds back a laugh and continues, "But then it was delivered and I'm not sure this was the tree we picked out."

The camera slowly pans away to show off the colossal tree that dwarfs the 5'8" actress.

Garner nervously grins up at the new festive addition to the house and marvels, "It's a little aggressive."

"Go big or go home," the "13 Going on 30" actress wrote in the caption, adding the hashtag "#aggressivechristmas."

Obviously, Garner's celebrity friends found her misfortune a complete riot.

Best friend Reese Witherspoon simply wrote. "Whoa!!"

Katie Couric joked, "OH EM GEE that tree has some serious BTE (big tree energy.)"

As to how the Garner family will decorate their personal Rockefeller-sized tree, or if they even have enough tinsel and ornaments to do it justice, the world will have to wait and see.
