Beyonce's Super Bowl halftime show preview was teased by the singer on Thursday and she also opened up on her past miscarriage.

The halftime show has been under a ton of scrutiny since the Beyone Presidnetial inauguration lip-syncing incident, but the singer appears to have gotten over it and looked ready to go in the video.

The video on YouTube, titled "Beyonce Super Bowl Halftime Show Rehearsal: Day 1," shows Beyonce's halftime rehearsals from day one abnd offers fans a tease of what is to come on Sunday. A black and white shot of Beyonce at a computer in the empty rehearsal hall starts the video before the card "Countdown to Touchdown" drops in.

Beyonce is singing in the background as shots of her and her dancers practice during the run up to the big game. The footage shows a large number of choreographed dancing and a large number of dancers and features a 10-second countdown as more footage is flashed before Beyonce leaves the hall.

Beyonec also put up a photo of her in a football face. CLICK HERE for the photo.

Chances are there will be more videos since the title has "Day 1" in it, but that remains to be seen.

The singer also opened up about her past miscarriage in her new HBO documentary :Life is But a Dream."

According to Yahoo, "About two years ago, I was pregnant for the first time," Beyonce says in the doc airing February 16, via Us Weekly. "And I heard the heartbeat, which was the most beautiful music I ever heard in my life."

"I picked out names," she adds. "I envisioned what my child would look like . . . I was feeling very maternal."

The singer was happy with the news, but then suffered some heartbreak soon after.

"I flew back to New York to get my check up -- and no heartbeat," she reveals. "Literally the week before I went to the doctor, everything was fine, but there was no heartbeat."

As previously reported on AccessHollywood.com, husband Jay-Z first revealed the couple's prior miscarriage in a song penned just days after Blue Ivy's birth.

Part of the set list for the halftime was leaked last week and revealed some of the songs that the former Destiny's Child singer will perform.

According to the report, Beyonce will be playing both solo tracks as well as songs from her time with Destiny's Child. Some of the new songs include "Bills, Bills, Bills," "Survivor" and the trio's new song, "Nuclear." Other rumored options include "Say My Name" and "Bootylicious."

Beyonce was embroiled in some controversy after being accused of lip syncing at the inauguration of President Obama, but sources say Beyonce will look to "knock them dead" at the Super Bowl.

"We all know Beyonce can sing," Master Sgt. of the U.S. Marine Band Kristin duBois told ABC News. "We all know the Marine Corps Band can play. We do not know why she decided to go with the pre-recorded music at the last minute."

Aretha Franklin came out and defended Beyonce to ABC News, saying:

"I thought it was funny because the weather down there was about 46 or 44 degrees and for most singers that is just not good singing weather."

Franklin sang at the inauguration in 2009 and said it was live.

"I wanted to give people the real thing and pre-recording never crossed my mind," Franklin said.

The backlash against Beyonce may take some headlines away from her Super Bowl halftime show performance, but it is likely that there won't any issues. People will keep an eye on her during the show to see if she is lip-syncing, but that doesn't mean the recording of her voice isn't authentic anyway.
