I (lie ) ! Its true I did see Madonna at tge supermarket

Nice try! If you want to correct and polish the sentence, here are a few options:

• I lied! It’s true that I saw Madonna at the supermarket.
• I lied. It is true that I saw Madonna at the supermarket.
• I lied—it's true that I did see Madonna at the supermarket. (casual style)
• I lied. It is true that I did see Madonna at the supermarket. (slightly more formal)

Notes:

• Use “the supermarket” with “the” (not “tge”).
• You can drop or keep “did” for emphasis: “I did see” sounds stronger than “I saw.”
• You can choose between a period, an exclamation mark, or a dash depending on the tone.
