Britney Spears‘s return to television has scored big with some critics — and in the ratings.

Monday’s episode of How I Met Your Mother featuring the pop star earned the CBS comedy its highest rating ever — netting a 4.5 preliminary rating among adults 18-49, according to the Hollywood Reporter. That means about 10.7 million viewers tuned in to watch Spears, making Mother the fourth-highest-rated show of the evening.

On the sitcom, Spears played a receptionist at a dermatologist’s office who develops a crush on a patient played by Josh Radnor. See a clip from Spears’s performance here. Monty Brinton/CBS
