Shaye Groves and Lauren White were arrested in connection with the death of Frankie Fitzgerald, 25, who was discovered dead on Sunday morning.
The father was discovered at an address in Havant, Hants, where Groves and White, both 26, were said to be living together.
Groves, who is wearing glasses and has a tattoo on her face in court, is charged with Mr Fitzgerald’s murder.
When White and Groves appeared in Portsmouth Magistrates’ Court in Hants yesterday, they only spoke to confirm their identities.
