Lady GaGa gushed about being so ''in love'' with boyfriend Christian Carino at her recent concert.

The 'Million Reasons' hitmaker praised the hunky CAA talent agent, who she's been dating since the beginning of the year, for being on hand to support her before she went on stage at Citi Field stadium in New York last week.

The 30-year-old singer also hailed her beau for helping her through hard times following her split from former fiancé Taylor Kinney last summer.

Speaking on stage, she said: ''When I went backstage, Christian, 48, was by the stairs making sure I was OK.

''The best part about being in love with someone is having them there to catch you if you fall.''

Sources have told The New York Post's PageSix column that the pair have been ''totally inseparable'' ever since they were spotted getting cosy at a Kings of Leon concert in January.

The 'Bad Romance' singer amicably split from 'Chicago Fire' actor Taylor, 35, in July after five years together.

A source previously claimed the former couple were contemplating rekindling their relationship in October, shortly after the blonde beauty admitted that she wouldn't be happy if Taylor started dating someone else.

When asked how she would feel if he started dating someone else, Gaga quipped at the time: ''I'm not going to f***ing throw a party!''

She added: ''I hate to sound like a hippie, but I kind of am one and so is he. We love each other, that's it. It's just about life changes, and we all go through different stages and we're focused on different things.''

''To be fair, I think that Taylor's pretty f***ing cool that over the years no matter what creative transformation that I've gone through, he's always been very supportive of that and loving.''
