The reality star, 28, has been pictured by Daily Star sporting a bloody nose and lip after being attacked while enjoying a pre-Christmas evening out in Derby.
A rep for Maria told Daily Star that she was "in shock" and didn't wish to talk about the incident at this time.
The spokesperson claimed it was a "random attack."
Police are said to be investigating.
Maria has not directly referenced the incident on her Twitter account, although she posted a link to the Daily Star story and said: "I've felt better…"
Among those sending well wishes Maria's way was Nicola McLean, who tweeted: "Big kisses and love to Maria Fowler. Anything I can do please let me know. There are [some] horrible people in this world."
Other social media users also chimed in with messages of support, wishing Maria a "speedy recovery."
Another wrote: "Omg! She looks awful bless her! I've always been a fan of hers so can't understand why someone would do that! (sic)"
Someone else commented: "I've bumped into Maria in Derby and she was lovely! Don't see any reason why people behave like this? #madworld."
Ahead of the attack, Maria appeared to be enjoying her night out. She had earlier tweeted images from a nightclub where she joked about meeting Santa and shared plenty of photos of herself looking happy.
Maria left TOWIE in January 2012.
