London - The Twitter shout-out is the benchmark for athletes of these Olympic Games, and a tweet from Justin Bieber is the pinnacle.But Gabby Douglas, who got a tweet from Biebs earlier this week, is pulling in a star-studded haul. Her list following her all-around gold medal included Michael Phelps, Oprah Winfrey, Timbaland and actresses Gabrielle Union, Elizabeth Banks and Octavia Spencer.It also touched off some jealousy as Douglas replied to Lil Wayne, but initially appeared to ignore Nicki Minaj."Oh wow, I tweeted about #Gabby earlier but she responds to [Lil Wayne] and not me? U know what? Ima fight u. I've had it!!!" Minaj tweeted.Douglas replied, triggering a love-fest back-and-forth between her and Minaj on Twitter."Hahaha I was trying to find it !!!!!!! I PROMISE!!!!!!!! THANK YOU SOO MUCH!!! OMG IM NUMB RIGHT NOW!!!!! #SPEECHLESS," Douglas tweeted.
