When someone says that something is "flattering" to them, they are implying that they feel gratified, honored, or pleased for being looked at in a positive light. For example, Emma Watson has used "flattering to me" here because she feels honored/gratified that she had so many movie makers interested in her as an actress. Ex: I felt flattered because my crush complimented my outfit. Ex: It was flattering to have beautiful girls try to chat me up.
