The L.A. district attorney also has surveillance video that should make it easier to prosecute the pop star in the separate egg-throwing case.

Another day, another troubling report about Justin Bieber.

The pop star, who was arrested in Miami Beach last month after cops suspected he was drag racing, was clocked doing 136 mph just hours before his early morning bust, according to TMZ.

Bieber hit 108 mph in his rented Lamborghini at 1:23 a.m., and he accelerated to 136 mph a minute after that, according to the GPS speed readout obtained by TMZ.

The GPS speed readout also shows that when cops said he was drag-racing, he was only going 27 mph.

Bieber was busted at 4 a.m. on Thursday, Jan. 23, on charges of DUI, resisting arrest and driving with an expired license. He's since pleaded not guilty and has a March 3 trial date.

Meanwhile, the pop star's still under investigation on allegations that he egged his neighbor's house in their Calabasas, Calif., gated community.

The L.A. county district attorney has two videos, TMZ reports, that should make it easy to prosecute the pop star. In one surveillance video, Bieber's shown in the vicinity of the area where the egging occurred at the time of the attack. In another video, in which it's too dark to see the pop star, you can hear what sounds like Bieber arguing with his neighbor in the middle of the egging, at one point saying, "F--- you! I got another one for you actually."

The L.A. county sheriff's department has recommended the D.A. file felony charges in the incident, citing the $20,000 worth of damage caused by the alleged egging.

The D.A. should decide how to charge Bieber this week, TMZ reports.
