Super Bowl 50 may just have gotten epic....
Maroon 5 is rumored to be in talks to be featured during the halftime show of the NFL championship game in Santa Clara, California on Feb. 7, 2016 and airing on CBS. What's more, a halftime show source tells ET that Adele is also a big possibility!
"Maroon 5 is just a rumor right now," the source reveals. "They have NOT been booked yet. It wouldn’t be a surprise if they perform as part of the show, but they are not the headliner. There are a few performers this year."

With Adele's new album, 25, dropping in November, the timing is right for a big game show.
"Bruno [Mars] was obsessed with having Adele join him two years ago but she wouldn’t do it," says the source. "I’m not sure if he has spoken to her yet, but it would make sense since she has an album coming out."
The reason this is a big deal is that ET learned in September that Mars has been asked back to perform for the Super Bowl 50 halftime show, as part of a larger group of performers.

In a letter posted to Facebook by the 27-year-old singer, Adele said the new record will be more introspective and less about relationships then her massively successful 23 album.
"My last record was a break-up record and if I had to label this one, I would call it a make-up record," she wrote. "I'm making up with myself. Making up for lost time. Making up for everything I ever did and never did. But I haven't got time to hold on to the crumbs of my past like I used to. What's done is done."

Another super star rumored to be on Mars' wish list is none other than Queen Bey!
"Bruno would love Beyoncé to perform again, but nothing has been said about that yet," the source says.
We don't know though... can the Super Bowl HANDLE an Adele and Beyonce halftime show? Let us know what you think!
Meanwhile, don't forget Adele and Lady Gaga were in the studio earlier this year and that's really what we all should be talking about. Watch the video below.
