George Lopez's show on TBS has been canceled, the network announced Wednesday, according to TMZ.

The last episode of the late-night show, which has been on the air for two seasons, will air Thursday night.

"TBS has reached the difficult decision not to order a third season of Lopez Tonight," the network said in a statement.

Lopez, 50, is not the only one with rating problems. TMZ reported Conan O'Brien's show, which aired just before Lopez's, pulled in an anemic 0.5 rating Monday in the key 18-49 demographic with 715,000 viewers. Lopez's ratings hovered around 0.2, with 400,000 viewers, TMZ said.

Lopez was the first Mexican-American to host a late night talk show on a US English-language network.
