Lea Michelle is ''falling in love'' with Matthew Paetz.

The 'Glee' star - who was left devastated when her boyfriend Cory Monteith died from a drugs and alcohol overdose last July - isn't concerned about rumours the 29-year-old model previously worked as an escort because she believes he's been honest about his past.

A source said: ''Lea and Matt are falling in love.''

However, the 27-year-old actress' pals are worried she's chosen the wrong guy again and will find herself heartbroken for a second time.

A friend told the US' OK! magazine: ''She goes from Cory, who was very sweet but clearly troubled with drugs, to a gigolo. It doesn't make sense to anyone.''

The pair met a few months ago on the set of her music video for 'On My Way', but chose to keep their relationship under the radar following her heartbreak with Cory.

The actress-and-singer previously revealed she grieves her late partner everyday, but she's trying to move on in her life.

She said:''You can choose to rise, which is what I'm going to try and do, but you have to be very strong.

''There's this grief with you every day whatever you're doing.''
