Songstress Lily Allen is nothing if not unpredictable, so when she revealed her self-imposed exile from the world of music back in 2009, fans let out a collective sigh of disbelief, not knowing if they had heard the last from one of the U.K.’s hottest and most controversial musical exports.

Luckily, it was only a temporary break and Allen’s triumphant return was celebrated in 2013 when she shared plans for her third studio album, ‘Sheezus.’ With her tongue-in-cheek nature firmly intact, Allen is currently out on the road in support of her May '14 release and recently took the stage at the sold out House of Blues in Boston, Mass. during her headlining run.

With a stage set that playfully boasted monstrous baby bottles at every corner fueled by LED lights, a purple haired Allen sauntered out on stage sporting a bedazzled skirt with a colorful array of baby bottles around the hem and immediately kicked into the new album's title track.

Her aura immediately enveloped the crowd like a warm embrace; it’s Allen’s candor and comfort level with her fans that makes her so likable. Shortly into her set she took a moment to announce that her throat was hurting her a bit and asked her fans to hang in there with her as she sprayed some magical elixir into her mouth to soothe her aching vocal chords. That was the end of it though -- while Allen tailored a few of the high notes throughout the evening, you’d never know that she was hurting. A true professional through and through.

While ‘Sheezus’ was certainly the star of the night, Allen’s two previously released LPs were heavily showcased as well with tracks like ‘The Fear,’ '22,' ‘Not Fair,’ and “F--- You,’ from 2009’s ‘It’s Not Me, It’s You,’ and ‘Smile,’ ‘LDN’ and ‘Littlest Things’ from her debut disc ‘Alright, Still.’ Allen took fans on a musical trip through her career throughout the 20-song set.

Allen has been criticized for calling out other artists and individuals through her music but at the end of the day, everyone is fair game to Allen including herself -- it's an even playing field. Sometimes self-deprecating, always bitingly sarcastic, Allen is hard not to root for. As she paraded through a bevy of wardrobe changes throughout the night in between witty exchanges of banter with the crowd, the warmth of her words resonated as truly genuine.

That may be where Allen rises above some of the rest in her field; she's open with her feelings and honest with her opinions, even if they aren't always popular. There's something to be said for that -- just ask her loyal fanbase.

Allen’s tour dates continue through the beginning of October -- check out her official website for the complete itinerary. In the meantime, enjoy our exclusive photos below:
