Patti Mallette "beliebs" in love. Among the millions of Bachelor fans watching the Monday March 11 season finale with rapt attention was none other than Mallette, the 37-year-old single mom to pop superstar Justin Bieber, 19. Superfan Mallette live-tweeted as Sean Lowe made his final choice between Lindsay Yenter and Catherine Giudici.

"OMG OMG OMG!!!!! NOOOOO. Seriously Sean???????" Mallette wrote towards the beginning of the broadcast. "This is definitely, by far.. the Most Dramatic Season Finale EVER! #thebachelor," continued Mallette, who gave birth to Bieber as a teen.

After entrepreneur Lowe, 29, bid adieu to Yenter and proposed to Giudici, 26, Mallette was pleased. "Ok that proposal was really amazing. She won me over in the end. And they ride off in an elephant together!? I'm happy 4 U. #thebachelor . . . *Sigh* #Soromantic"

Mallette -- who once went on a date with newly single Bachelor host Chris Harrison -- then cracked up when her tweets showed up during the live After the Rose Special, and ogled over Giudici's bling. "That ring is stunning!!! #MenTakeNotes."

Back in October, Mallette tweeted a photo of herself with Harrison 41, backstage at a Bieber concert. "It was just a fun, friendly night!" a source close to Mallette told Us Weekly. "No real sparks, but they had a blast . . . She's known Chris before and they are acquaintances. No real romance though."
