Rumors that Katy Perry and John Mayer are back together recently sparked especially when they were spotted enjoying a Super Bowl after party with Missy Elliot.

According to Us Weekly, Mayer was spotted waiting on the side lines for his former girlfriend after her 2015 Super Bowl performance.

Weeks prior to this, Mayer and Perry were also spotted having dinner at the West Hollywood restaurant in the Sunset Tower Hotel, a hot spot in Los Angeles that is said to be not a good place for celebrities who want to avoid being seen in public.

An eyewitness told Page Six that Mayer and Perry "walked in together, arm in arm, and the whole room literally fell silent."

Mayer and Perry confirmed their split exactly a year ago.

The NFL reportedly selected Perry over Rihanna and Coldplay because her pop brand may help save the reputation of the league, which has been tainted recently by issues on player safety and domestic abuse.

Also, as compared to Bruno Mars in 2013, Perry could perform more hits during an act due to her more flexible schedule during the Super Bowl, which will air on Feb. 1, 2015 on NBC.  She is not set to perform in any shows in 2015 until Feb. 16.

In 2013, the Super Bowl had a record-breaking audience of 111.5 million viewers.

Moreover, unlike Rihanna, Perry is said to be family friendly and she is less likely to make a scene similar to Janet Jackson's so-called wardrobe malfunction in 2004 and M.I.A.'s bird-flipping incident in 2012.
