In praise: Amber lauded her friend for giving a stellar performance earlier that evening

Amber appeared to enjoy her night out after just giving birth to her son - with fiancé rapper Wiz Khalifa - two months ago.

Rihanna had taken to the stage earlier in the night dressed like pop royalty.
The Diamonds (In The Sky) artist wore a gold embroidered jacket and thigh-high leather boots.
The petite songstress completed the outfit with black and gold briefs, a leather bikini top, and a diaphanous shirt.
But for her backstage antics the Barbados native slipped into something a little more casual.

Earlier in the evening the pop star, who is currently on her Diamonds world tour, asked the captive audience: 'How many of you are in love?
'How many of you hate love? How many of you don't f**king understand it? I'm in that group.'
The confession came, according toPeople.com, as an introduction to her new song What Now from her latest album.
The lyrics for the new track are quite revealing: 'I've been ignoring this big lump in my throat. I shouldn't be crying, tears were for the weaker days.
'I'm stronger, now what, so I say. But something's missing.'

On the rocks: Chris Brown and Rihanna at the Grammy Awards in Los Angeles, in February

Rihanna has apparently been finding it difficult to see her 23-year-old on/off beau Chris Brown, who is gearing up to release his new album X.
The couple - who reconciled last year even though Chris is still on probation for beating her in 2009 - were spotted partying separately at different Los Angeles hotspots over the weekend.
But friends of the couple insist they are still together and just have a lot going on.
