Country star Miranda Lambert is set for her first No. 1 album on the Billboard 200 chart -- and her best sales week yet. The singer's new release, "Platinum," could sell upwards of 175,000 copies in the week ending June 8 -- according to industry forecasters.

The Billboard 200's new top 10 will be revealed on Wednesday, June 11.

"Platinum's" arrival would mark Lambert's best week ever, and the largest sales frame for a country female artist since Taylor Swift's country/pop crossover set "Red" did 241,000 in the week ending Dec. 30, 2012, according to Nielsen SoundScan. (It debuted nine weeks earlier with 1.2 million.)

Outside of women named Taylor Swift, the last country queen to sell more than 175,000 in a week was Carrie Underwood, when her "Blown Away" album bowed at No. 1 with 267,000 in the week ending May 6, 2012. (Coincidentally, "Platinum" features a duet with Underwood called "Somethin' Bad.")

"Platinum" was released on June 3, and is Lambert's fifth studio release.

Each of her albums have started with successively larger debut weeks. Her first release, "Kerosene," bowed at No. 18 in 2005 with 40,000. She followed it up with 2007's "Crazy Ex-Girlfriend" (No. 6 with 53,000), 2009's "Revolution" (No. 8 with 66,000) and 2011's "Four the Record" (No. 3 with 133,000).

"Platinum" should also easily secure Lambert her fifth straight No. 1 on the Top Country Albums chart.

After Lambert, look for rapper 50 Cent to nab the next-highest new entry on the Billboard 200. His new "Animal Ambition" album (his first independently-distributed set after departing Interscope Records) might sell upwards of 35,000 -- good enough for a top 10 debut.
